A simple way to add responsive (breakpoint-specific) blocks in Gutenberg

The new WordPress Block Editor (a.k.a. Gutenberg) has improved immensely over the years, to the point where I am now willingly (although occasionally grudgingly) using it as my main development platform for client sites.

One area where it really falls down though is in smartly handling responsive breakpoints. There is some effort to make it responsive-friendly (though it’s definitely not “mobile first”), but there are really weird holes, like the fact that there’s no built-in way to apply consistent left and right margins on text content at smaller screen sizes; once you’re below the defined content width, if you don’t manually configure your theme to add padding/margins to headings, paragraphs, etc., and they don’t have a defined background color, the text will bump right up against the edges of the screen.

That’s not the problem I’m here to solve at the moment, however. Instead, I want to focus on a handy little tool I’ve been using in my WordPress development for over a decade: specialized CSS classes to designate blocks of content as only appearing on phones, or not appearing on phones.

By “phone” here I just mean the smallest standard breakpoint. I’m using the WordPress convention (at least it used to be the WordPress convention; I don’t feel like I can trust anything anymore) of setting that at the slightly odd (although even) value of 782 pixels.

What can you do with this? Once you have CSS classes that designate a block as only appearing on phones or not appearing on phones, then you can easily tailor your output to certain screens. Obviously (at least, I hope it’s obvious) this is not the ideal solution; it means you’re delivering HTML content — potentially redundant HTML content — that will not be seen by some users. But nothing in web development is perfect, and this can be a convenient way to get out of a pinch when, for example, you have a very complex desktop layout element that simply cannot be adapted in a usable way on phones. You can just hide that element on the phone breakpoint and, if desired, present the same content in a more simplified way to only phones. (Again… only if you can’t achieve a usable phone experience on the same HTML block via media query-specific CSS.)

OK, let’s get down to it. The first thing you need to do is register a couple of block styles. I am only making these styles applicable to the Group block, because that seems like a logical way to rein it in. Any block can easily be wrapped in a group, so if you need this feature, just do it.

register_block_style('core/group', array(
  'name' => 'no-phone',
  'label' => 'No phone'
));

register_block_style('core/group', array(
  'name' => 'phone-only',
  'label' => 'Phone only'
));

That should go into your functions.php file or wherever in your theme you are defining block characteristics. Ideally it should be in a function that is executed on the init action. Next, you need to make sure you’ve got a custom block style .css file enqueued for the Group block. You can place this wherever is appropriate within your theme; I happen to have a nested assets/css/blocks folder where I put mine. Here’s that bit of code, also for your function that runs on init.

wp_enqueue_block_style('core/group', array(
  'handle' => 'my-theme-core-group',
  'path' => get_theme_file_path('assets/css/blocks/core-group.css'),
  'src' => get_theme_file_uri('assets/css/blocks/core-group.css'),
));

And then in the referenced core-group.css file, you’ll need this:

@media screen and (max-width: 782px) {	
  .wp-block-group.is-style-no-phone {
    display: none !important;
  }
}

@media screen and (min-width: 783px) {
  .wp-block-group.is-style-phone-only {
    display: none !important;
  }
}

Now in the Block Editor, when you switch to the Styles tab when focused on a Group block, you’ll see your new style options:

Q: Should I build an app? A: Probably not.

One of Room 34’s long-time agency partners emailed me today asking if we build mobile apps. It was a simple question. The email itself was only one sentence, and, initially, so was my response:

We haven’t yet, but it’s been on my radar to potentially pursue.

Then I gave it more thought, and realized I should flesh out that answer a bit, with an explanation of why we haven’t developed any apps. Yet.

Honestly I’m sure part of the reason is that we’re a web development shop. That’s what we do. I’d be lying — to myself — if I didn’t acknowledge that there’s some amount of a desire to “protect my territory”; apps are a threat to the web development business. Adapt or die, etc. But I think apps have been around long enough now to show the web isn’t going to die. The nature of the web and how we use it is changing, but the web itself is still a huge part of the Internet experience, and its underlying technologies (HTTP, SSL/TLS, XML, and JavaScript or JavaScript-derived tools like JSON and AJAX for sure) are fundamental to how any Internet-connected mobile app works!

Yet, I still make the argument that a lot of people who think they need an app really don’t. All they need is a mobile-friendly (ah-hem, responsive) website. So that was the rationale I laid out in the rest of my email response:

Most of the time when people have approached us about an app, I have convinced them that it didn’t make sense for their needs to do an app. But there are definitely legitimate uses.

A few reasons not to do an app, and just do a mobile website instead:

  1. Apps are more expensive to develop.
  2. Apps require more promotion to achieve awareness.
  3. Users have to make the choice to seek out the app in the App Store / Google Play and download it.
  4. Often client requirements for the app don’t involve anything a mobile website can’t do.

On top of those reasons, #2, and to some extent #3, generally means you need a marketing website to promote the app anyway, and if the user is already coming to the website, if #4 applies, there’s really no value left in creating the app, unless it’s a paid app or has ongoing in-app purchases to achieve any kind of ROI.

Reasons to create an app:

  1. Advanced features that require native device functionality, that a website can’t achieve.
  2. The app itself is a (reliable) source of revenue.
  3. The app is for an industry where it might be preinstalled on users’ devices, or required for their work.

What I didn’t mention is that the app “gold rush” is over. The potential in 2015 of a new venture to get rich with an app is approaching the odds of winning the lottery and getting struck by lightning simultaneously.

The only reason to create an app now is if it’s filling a genuine need that can’t be met with a mobile website, and it has the necessary value to the end user that the higher barrier of entry into using an app, compared to a website, can be overcome.

Responsive Web Design: A Practical Approach (Part One… Again)

With exactly three posts here all summer, the last being nearly two months ago, it might be reasonable to assume this blog had been abandoned. Wrong! I have simply been so busy, building so many responsive websites, that I haven’t had time to gather my thoughts to share in anything longer than 140-character bursts.

“‘Responsive’ websites?” you say, and I hear the internal quotation marks in your voice. Yes. If you don’t know what responsive web design is… well, let’s be honest. You found this post, if you found it at all, when you googled “responsive web design” so I suspect you have at least a passing familiarity with the term. So let’s get started.

(Actually, before we get started, a quick note: astute observers may… um… observe that I wrote a seemingly identical post to this one back in June. And yes, that’s right. But after a summer immersed in this stuff, rather than continuing from there with “part two” it felt better to start over from the beginning with a more in-depth introduction.)

Getting Started, or, rather: How I Got Started

I’ve owned an iPhone for about 4 1/2 years now, and one of the first things I noticed shortly after it became the hottest thing around was that everyone was suddenly creating mobile websites. There were even services created just to help you convert your website into a mobile website. But it was always a separate experience (usually with a domain name that started with m.) and invariably an inferior one.

A lot of websites still do that, and it still sucks. It’s two separate websites, which is bad for users — often content doesn’t make it to the mobile site, and when that happens there’s no easy way to get to it on the desktop version — and it’s bad for site owners — double (or more) the work.

But about a year ago I started to notice a new approach, one that didn’t require two separate websites, and one that, owing partly to how quickly it caught on with the superstars of web design, usually yielded much better looking results: responsive web design (which I will henceforth lazily refer to as RWD). RWD uses CSS3 media queries to detect the window/screen size the page is displayed on, and changes the layout of the page to suit the screen. On the fly. Same page. Same CSS.

So there is no mobile site, no desktop site. There’s just the site. And it looks great on any screen.

In theory.

Of course, this solution is not perfect. But it is better in so many ways — standards compliant, future-proof, user-friendly, easy to maintain — that it is clearly the optimal solution for mobile websites today.

Getting Started (you, this time)

Before you delve into RWD, there are a couple of things you need to know: 1) HTML5 and 2) CSS3. More specifically, you need to embrace the concept of semantic HTML fully, as a well-structured HTML document is essential to the responsive approach.

I assume if you’re thinking about RWD, you’ve long since abandoned table-based layouts, and you probably don’t even remember the <font> tag existed, right? Right. But for RWD to work well you need full separation of your visual design from your document structure.

My personal preference is to take this to an extreme: I never even use <img> tags except in body content. All visual elements of the layout are contained in my CSS, even logos, and I avoid using images wherever possible. By taking full advantage of the visual effects offered by CSS3, and accepting “graceful degradation” in older browsers (or, in reverse, “progressive enhancement” in newer ones) — a topic we’ll get to in a bit — you can create a lean, well-structured site that is ripe for the responsive treatment.

Building Blocks

Nothing starts from nothing. (Whoa, that’s heavy.) And certainly a responsive website doesn’t (or generally shouldn’t) start from scratch. There are three building blocks that I now include in every site I build out:

reset.css

Created by CSS guru Eric Meyer, reset.css is a handy little file that removes all styling, which can vary between browsers, from all HTML elements, allowing you to “reset” the design and start with a clean slate. Just remember that it means you’re going to have to redefine everything — I guarantee your CSS file will eventually contain strong { font-weight: bold; } and em { font-style: italic; } but that’s the price you pay for complete control.

html5shiv.js

Developed (or at least maintained and expanded upon) by Remy Sharp, the purpose of html5shiv.js is to enable support for new HTML5 elements in older, but still widely used, non-HTML5 browsers like Internet Explorer 8 and earlier. You don’t have to use the new tags like <article> and <nav> to do RWD, but it’s fun, and feels like the future.

jQuery

There are a handful of popular JavaScript libraries out there whose goals are generally to 1) standardize inconsistent JavaScript across browsers, and 2) make working with the DOM easier, so you can do cool, standards-compliant, cross-browser compatible animations and interactivity with just a line or two of code. jQuery is arguably the most popular of these, and is my personal favorite. Again, this is not strictly required for RWD, but I use it all the time, and often in ways that enhance the capabilities of my responsive layouts. (One specific example: it’s great as a foundation for resizing complex elements like slideshows… of course, for that matter, it’s great for making the slideshows in the first place.)

Finding Your Break(ing) Point(s)

The grand vision of pure RWD is a fully fluid layout that scales dynamically to any screen size, and a grand vision it is indeed. But we are living in an imperfect world, with many factors to consider.

In my case, I typically work with outside designers. Designers who appreciate and support RWD but are not immersed in its intricacies like I am. And I don’t want them to have to be. So as a hybrid developer-designer, I make use of my somewhat unusual but not especially unique skill set to handle the responsive adaptations for them. They just deliver a “regular” web design to me, I build that out, and then I adapt and scale and shift things around as needed for the smaller screen sizes, doing my best to stay true to the spirit of the original design.

There are two keys to making this approach work:

  1. Get the designs in Illustrator format, not Photoshop. (No, seriously. You’ll find out why in a bit.)
  2. Be prepared to start thinking about break points and accept that a perfectly fluid layout is not in your immediate future.

To understand break points, you need to understand common screen dimensions. You also need to understand the importance of margins to an aesthetically pleasing layout.

For years the target screen size for web design has been 1024×768 which, delightfully, is also the effective resolution of the iPad. (Yes, the newer iPads have a high-resolution “Retina Display” which is 2048×1536, but CSS pixel measurements are “pixel-doubled” on these displays, so you don’t really need to think about high-res too much, except when it comes to images, and we’ll discuss that in a minute.)

So, we can (still) start with 1024×768. But that doesn’t mean your design should be 1024 pixels wide. You need margins, both for stuff like window “chrome” (borders, scrollbars, etc.) and also just to give your content a little breathing room. A commonly accepted standard width to use for web designs is 960 pixels, and I still stick with that.

This can sometimes cause some confusion for designers who are used to the fixed palette of a printed page. Your content can/should go all the way to the edges of that 960-pixel layout, and you still need to think about what comes outside of that area. So it’s good when you’re designing to think of foreground and background. Have an arbitrarily huge background canvas, with a 960-pixel-wide by whatever-pixel-tall box floating top-center over it, where your foreground content will go.

But I digress. We start with 960. That’s our maximum break point. (OK, if your audience is primarily looking at the site on 30-inch displays, you might want to consider an additional larger break point at 1200 or so.) Then we move down from there. I like to think of it like this:

Device/Screen Type Screen Width Content Width #wrapper CSS
Large computer displays (optional) 1280 and up 1200 margin: 0 auto;
width: 1200px;
Computer/iPad (landscape) 1024 960 margin: 0 auto;
width: 960px;
iPad (portrait) 768 720 margin: 0 auto;
width: 720px;
Small tablets/phones Varies Fluid margin: 0 auto;
width: 90%;

The “small tablets/phones” layouts typically collapse to a single column and are the only truly fluid layouts I use; the larger break points go to fixed widths, which makes for easier scaling of columnar content.

Note that I typically follow the convention of placing everything inside my <body> tags inside a <div id="wrapper"> tag, which allows me to apply CSS to the overall page body and separate CSS to the foreground content (what’s inside the “wrapper”).

Occasionally I will split “small tablets/phones” into two separate break points, with small tablets somewhere between 500 and 640 pixels. I may also change the content widths somewhat to suit the specifics of the design.

Mobile-First Sounds Great, but Let’s Be Honest: It’s Really IE8-First

Earlier in the year, Luke Wroblewski took the idea of RWD a step further with his inspired vision for Mobile-First web design. Initially I wholeheartedly embraced mobile-first, but I’ve since reconsidered.

What is mobile-first? It’s RWD, but instead of starting from the desktop layout and using CSS3 media queries to adjust the layout to smaller screens, it starts from the small screens and works its way up. The main benefit of this approach is that it allows you to prevent mobile devices from loading unnecessary assets (images, etc.) that they won’t actually use.

There’s a major downside to mobile-first, however, at least in my experience trying to implement it: there are still a lot of people using Internet Explorer 8 (and earlier), which does not support CSS3 media queries. So unless you create an IE-specific stylesheet (using conditional comments), IE8 and earlier users will be stuck with a strange variation on the phone version of your site.

So after building a few mobile-first RWD sites, I have abandoned that approach, and gone with what could be called an IE8-first approach. I am not really building to IE8. I work primarily on a Mac, and I preview my work in Chrome while I’m developing. But what I mean is I’ve gone back to that standard 1024×768 screen as the baseline for my CSS, with CSS3 media queries for the smaller screen sizes (as well as for print and high-resolution displays, the latter of which is next up).

Getting Retinal

Remember earlier when I said your designs should be in Illustrator rather than Photoshop? Here’s why: high resolution. Sure, you can change resolution in Photoshop too, but… wait, you’re not still slicing-and-dicing, are you? By working with discrete objects in Illustrator, resolution-independent and, when possible, vector-based, you have the maximum flexibility when you render these objects out as 24-bit PNGs with alpha channel transparency. (You are doing that too, right?)

Starting with the iPhone 4, Apple introduced the “Retina Display” which is their marketing term for, basically, screens with pixels too small for you to see. The goal is to achieve a level of resolution on an LCD screen that rivals print. The exact pixels-per-inch varies from screen to screen, and is not really too significant. The key point is that above a certain pixel density threshold, CSS treats all pixel-based measurements as pixel-doubled. As I noted above, although the current iPad screen resolution is 2048×1536, its effective pixel size in CSS is still 1024×768. There is a practical reason for this (if CSS stuck with the actual pixels, all web pages would appear absurdly tiny on such a screen). But there’s also a practical downside: most images on most web pages are now being scaled up in the browser to these pixel-doubled dimensions, resulting in a blurry appearance.

But here’s something really cool: you can specify the display dimensions of an image in CSS, and the browser will scale the image down on-the-fly. This has been the bane of many web developers’ existence for years, where people who didn’t know better would upload a very large, high resolution photo and scale it down in the page, resulting in ridiculous download times as the image slowly drew in on the page.

Used effectively, however, this characteristic provides an extremely easy way to make images high-resolution on displays that support it. By using CSS to scale the dimensions of an image to 1/2 its actual pixel size, the image will display in full resolution on screens that support this.

Of course, doubled dimensions mean quadrupled pixels, and depending on the details of JPEG or PNG compression, the high-resolution images may be more than four times the file size of their standard-resolution equivalents. So it’s nice to, again, use CSS3 media queries to only deliver these high-resolution replacement images to screens that can display them properly. (This will be demonstrated in the full example code below.)

You Say Graceful Degradation, I Say Progressive Enhancement

The matter of graceful degradation and/or progressive enhancement (depending on how you look at it) is tangential to RWD, but it’s something you’re likely to be dealing with as you build a responsive website.

Not all browsers support all CSS3 capabilities, but that doesn’t mean you shouldn’t use them. I’m especially fond of box-shadow and border-radius, and in working with RWD you’ll probably get quite familiar with background-size as well. Remember that most of these newer capabilities will probably need to include vendor prefixes (like -moz- and -webkit-) as well. It’s cumbersome, and will probably be as painful to clean up as <blink> tags in a few years, but for now it’s the way to get things done.

The biggest challenge with progressive enhancement may well be convincing site stakeholders that it’s OK for the site to look (subtly) different in different browsers. Then again, if you’re doing RWD, that should be a given.

So, What Does This Actually Look Like?

As I’ve iterated my RWD approach this summer, I’ve inched closer and closer to a standard template I can use to start a new website. I feel it’s not quite there yet, but my basic CSS file structure is standardized enough that I can share it here. In a subsequent post, I hope to provide a zip download containing a full template file set for creating a new responsive website.

Here’s a rough example of what my typical CSS file looks like. Again, personal preferences dominate here: I like to write my CSS from scratch, and I typically organize it into three sections: standard HTML (basic tags), CSS classes (anything starting with a period), and DOM elements (anything starting with a hash mark).

The idea is that we’re going from general to specific. Within the standard HTML and CSS classes I alphabetize everything, so it’s easier to find things to change them as I go. Within the DOM elements I try to keep everything in the order it actually appears in the HTML structure. (I also alphabetize the properties within each element definition… but that’s just because I’m anal retentive.)

The Test Suite

Of course, all of this work means nothing until we’ve seen what it actually looks like in the web browsers on these different devices. To that end, a decent test suite is essential.

One cool trick about RWD, which is not only useful to dazzle clients when pitching a RWD approach to their websites, but is also helpful for quick testing as you go, is that the responsive approach works simply by making your browser window smaller on a computer. So you can shrink the window down and approximate what the site will look like on a tablet or a phone without actually having one in your hand at all times.

But before you go live, you do need to test it for real on different devices, just like you need to test in different browsers. The table below shows my test suite. It’s not comprehensive, but it’s practical, and it all fits in one small messenger bag.

Give Me Something I Can Print!

You may have noticed in the full example CSS above that I included CSS3 media queries for print. The need for decent print output will vary by project — different sites’ audiences may be more or less inclined to print out pages. In general I think of printing out web pages a bit like I think about… well, honestly, I can’t even think of a good analogy. You just shouldn’t do it. But sometimes it has to happen. I won’t be exploring the infuriating nuances of print CSS here, other than to say that if you do need to support printing, the code provided in this sample is a good place to start. (Sadly, although I use it regularly, I neglected to make note of its source. If you know where it’s from, please let me know in the comments.)

Where Do We Go Now?

OK Axl, hang on. I know I’ve dumped a lot on you here to think about, without necessarily providing enough specifics. But that’s kind of the point: in order to do this right, you really need to learn it for yourself and gain the experience of building RWD sites directly. This is what has been working for me but my approach is certainly neither the only nor the best way, I’m sure.

My hope is to follow up this post with a “Part Two” entry this time around, where I get into more of the specifics of an actual example website. In the meantime, experiment and discover! And be sure to check out the entire A Book Apart series, as they provide the conceptual and detailed knowledge needed to get started with this exciting new approach to web design.

Practical responsive web design, part one

I’ve been wanting to write this post for a while, but I’ve been too busy writing code instead. Plus, the techniques are evolving and changing so fast, that by the time I finish a project, the way I built it is already obsolete.

Now, with the Breaking Development Conference in town and a few recent responsive site launches under my belt, it seemed like a good time to write up a summary of what I’ve learned, what I’m doing, and where I think all of this is going.

First, a quick aside. I didn’t attend the conference. I would have liked to, but as an independent developer I never seem able to justify the standard $500-per-day rate most conferences charge. That doesn’t mean the conferences don’t have value; they’re just not for me.

Before we begin

There are a few caveats I want to lay down before I start talking about responsive web design:

This stuff is changing… fast. Anything I write here may become foolishly out of date by the time I hit the “Publish” button. Responsive web design is a work in progress, and there are no rules (yet).

What I’m doing may not be “by the book,” proper-name Responsive Web Design. The book is great, and there are “experts” who have much deeper knowledge of these strategies than I do. But as I said above, there are no rules (yet). I want to describe the practical techniques I am employing on actual live web projects, under often less-than-ideal circumstances.

Every website is different. The company is different. Its audience is different. The content and style and context where it will be viewed are different. The balance between showing off fancy new features on high-resolution tablet displays and supporting corporate IT departments that are still straggling with Windows XP and Internet Explorer 6 will vary. In short, what I am doing may not work for you. But I hope it can give you some ideas that will.

A practical baseline

My goal with responsive design is to get the biggest “bang for my (client’s) buck.” I recently read a about a study that found almost 4,000 different Android devices in a site’s access logs, with many of them only appearing in the logs once. It is not possible to account for all of these variations. And, after its primary goal of providing an optimal user experience across a variety of devices, not needing to account for each of them individually is the second biggest purpose of responsive design. (That’s also, arguably, its biggest practical benefit.) By building on a fluid, flexible structure from the beginning, a site will look good regardless of slight variations in its presentation.

But I’m not starting from scratch. I work with a number of designers who deliver their work to me in a variety of formats (usually Adobe software). They’re tremendously talented, but they don’t all have a full working knowledge of fluid grids and all of the other considerations that go into responsive web design. So my job is largely to translate these “traditional” web designs into something that works, more or less, with a responsive approach.

I’m targeting three basic screen types: computer (desktop or laptop, including iPad in horizontal orientation), tablet (primarily iPad in vertical orientation, but also smaller tablets like the Kindle Fire or the Nook Color), and smartphone (primarily iPhone, but also Android and Windows Phone). Additionally, I am trying to balance a Mobile First approach with support for Internet Explorer 7 and 8. (I am fortunate to be in a position not to need to worry much about IE6 anymore, and IE9 plays well with CSS3 media queries.) In some cases I am also targeting “very large” computer displays, those with a horizontal resolution of 1280 or above, with a scaled-up layout.

So, instead of accounting for 4,000+ different screens, I’m aiming at 3 (or 4) general screen categories. I am also accounting for two basic browser categories: IE 7 and 8, and everything else. (Yes, if you approach it in the right way, it’s really that simple. Almost.)

Fixed, yet flexible

With this “practical baseline” in mind, and working primarily with traditional fixed-width web designs as a starting point, I’ve established break points (widths at which the layout changes significantly) at around 700 pixels (varying by site between 640 and 720); at 960 pixels for the “standard” computer (and horizontal iPad) layouts; and, for the “very large” displays, at 1200 pixels. This allows for a traditional fixed-width web design approach to be used, rather than accounting for a completely fluid layout across all screen sizes. It may sound like a cop-out, but I find it to be a very helpful way to get things done when collaborating with designers who are not living and breathing this stuff the way I do every day.

For screens below my “around 700” threshold, I drop into a fully-fluid, single-column layout targeted at the smartphone user experience. In these cases there may be other significant changes to the layout, such as collapsing content blocks into expandable buttons, allowing users to quickly see what’s on the page without having to scroll endlessly. (This is not a radical invention of my own… it’s more-or-less how the mobile version of Wikipedia functions.)


In part two, I will get into the details of how I built out a pair of recent websites, including a few code examples, to show how the HTML and CSS fit together, and how I balance the seemingly incompatible worlds of mobile-first and IE8.

A brief rant against “mobile” websites, and in praise of CSS3 media queries

This morning, as I do on most mornings, I eased the transition between my peaceful slumber and the mayhem of conscious life by lying in bed, catching up on the goings-on of humanity on planet Earth with the help of my iPhone and the Internet.

This usually consists of checking Twitter, Facebook, and my Google Reader feeds, but when that isn’t enough, I’ll occasionally search the web for whatever random piece of information crosses my stream of consciousness. Today that happened to be the Tim and Eric comedy tour that’s currently underway, since I’ll be seeing it when it arrives in Minneapolis on Wednesday. So I googled Chrimbus Tour review and one of the first links that came up was a review on BuddyTV.

BuddyTV is not a site I think of often. I believe I was vaguely aware of its existence before today, but I didn’t know what it was all about and I never had any inclination to visit it. But I was certainly happy and willing to click the Google link and read its review of the Chrimbus Tour.

Unfortunately, the site did not reciprocate that happy willingness. Instead of taking me to the desired review, it detected I was arriving via iPhone, so it shunted me off to an annoying splash page imploring me to download the BuddyTV iPhone app. No thanks, I really just want to read the article I came here for in the first place. Oh, great! You’ve provided an “Or continue to BuddyTV.com” link at the bottom. Thanks!

But — and this is so often the case in this scenario — that link did not helpfully take me to the article I wanted. (And as a web developer, I can tell you it is not at all difficult to make it do that.) Instead it just went to the BuddyTV home page. Now what? I’ll tell you now what: I closed Mobile Safari and got out of bed. Not only did I not download their app; I didn’t expose my eyeballs to any of the ads that pay for their website; I didn’t get to read the article I was interested in; and I was left with such a negative impression of the site that it drove me to this public rant.

All of this is not really to single out BuddyTV for its bad behavior, though. BuddyTV is just one site among many I’ve encountered over the past couple of years that all adhere to this same pattern of deplorably ill-conceived UX design. Surely this is not the reaction the owners of these sites hope to elicit. But it’s exactly what happens with me, every time, and I’m sure I’m not alone.

There is a solution.

We frequent users of web browsers on mobile devices just want to see your site. We want to see the same pages we’d see on our computer. The same content. But it doesn’t hurt to have that content optimized for the mobile browsing experience. Resized to the smaller screen. A streamlined layout that’s easier to navigate with a touchscreen. But, fundamentally, the same experience.

While there are some tools out there to help turn a regular website into a mobile website (most notably Mobify), there’s a far easier solution: CSS3 media queries.

CS-what media what now? CSS3 media queries are, simply, a set of stylesheet definitions that are applied to a web page selectively depending on certain characteristics of the media the page is being viewed on, most notably, screen size.

With CSS3 media queries, you can define an entirely separate set of stylesheet attributes to be applied only when the user is visiting the site from a small screen. Or an extra large screen. Or you can describe a bunch of intermediate sizes, so with the exact same HTML content the user will see a perfectly laid-out page, optimized to their screen, whether that’s an iPhone, a netbook, a “standard” computer monitor or a 30-inch Apple Cinema Display.

I’ve begun working more extensively with CSS3 media queries on some of my own projects lately, and I am very excited about the potential. If you’re a web developer or designer, you should learn about CSS3 media queries now. And if you’re a website owner, you should know that “mobile” sites are sooo 2008. Now you can have your cake and eat it too. You can have the best of both worlds. Insert cliché here. Just don’t subject your site visitors to any more obnoxious plugs for your iPhone app, or dump them thoughtlessly on your mobile home page with no way of tracking down the article they were coming for. It’s not fair to your users, it’s not fair to your public image, and if you’re supporting your site with ads — or, for that matter, if you’ve been convinced to drop a ton of extra cash on developing a separate mobile site, or an iPhone app that just displays your site’s content anyway — it’s costing you money.
