WebKit Isn’t Breaking the Web. You Are
It sounds like something from a galaxy far, far away, but in truth it was not that long ago that the web was littered with sites that proudly proclaimed “works best in Internet Explorer.” Thankfully those days are over. IE6 no longer dominates the web.
But, while IE6 may be a thing of the past, the root problem — websites that work in one and only one web browser — sadly, remains.
This time the culprit is WebKit, the rendering engine that powers the browsers on the iPhone, iPad and Android phones. But what’s different about this round of monoculture is that, unlike IE 6, the WebKit developers haven’t done anything wrong. It’s web developers that have created the WebKit-only web.
Instead of writing code that will work in any browser, which might mean adding an extra three lines of code to their CSS rules, some of even the largest sites on the web are coding exclusively for WebKit.
The problem is bad enough that on Monday at the CSS Working Group meeting, Microsoft, Mozilla and Opera announced that each are planning to add support for some -webkit prefixed CSS properties. In other words, because web developers are using only the
-webkit prefix, other browsers must either add support for
-webkit or risk being seen as less capable browsers even when they aren’t.
The danger is that if other browsers implement -webkit prefixes then the entire CSS standards effort will be broken. Instead of coding against a single CSS specification developers will need to code against changing vendor prefixes. As CSS Working Group co-chair, Daniel Glazman, says, “I don’t think this is the right way. And this is the first time in this WG that we are proposing to do things that are not the right way.”
Vendor prefixes like
-moz were designed to help web developers by allowing browser makers to implement CSS features before the official standard was published. Prefixes were intended to help speed up the process of adding new features to the web and, used properly, they have worked. Unfortunately they’ve also been widely abused.
WebKit is currently the dominant mobile browser in the mind of most web developers (that Opera is actually the single most widely used mobile browser). But even the perceived dominance of WebKit is not the real problem. The problem is — just as it was last time — that web developers are developing exclusively for WebKit.
To be clear, Firefox, IE and Opera also support these features. In most cases, the -webkit properties being used have -moz, -ms and -o prefix equivalents for use in the respective browsers. Popular CSS 3 features like border-radius, transforms, gradients and animations work in all modern browsers. Developers simply need to add those three additional lines of code to make their websites compatible with Firefox, IE and Opera. But they aren’t doing that.
That the problem lies with web developers, not the browsers, led Glazman, to put out a call for action, asking web developers to “stop designing web sites for WebKit only, in particular when adding support for other browsers is only a matter of adding a few extra prefixed CSS properties.”
Neither Glazman, nor anyone else is suggesting that Apple and Google should stop innovating or stop implementing new features as fast as they can. As Tantek Çelik, a Mozilla representative in the CSS WG, says in the minutes of Monday’s meeting, “I think it’s great that Apple wants to innovate as fast as they can…. I don’t want Apple to slow down in innovation and implementing new things. That helps the Web grow and innovate.”
At the same time both Apple and Google have set some bad examples by building a number of WebKit-only demos that might be part of what lead some developers to conclude that only WebKit supports such features. That has also spilled over into the world of tutorials where even sometimes even standards advocates showcase -webkit in their sample code while ignoring -moz-, -ms- and -o-*.
What makes the current -webkit-only epidemic all the more depressing is how easy it is to solve — just use prefixes they way they were intended. Thanks to modern toolkits you don’t even need to write any extra code. Preprocessors like SASS and LESS make it easy to output five lines of prefixed code with a single mixin. Not a fan or SASS or LESS? No problem, just use cssprefixer, which parses your CSS and adds any prefixes you need before you publish it to the web (there’s also a client-side auto-prefixing solution if you prefer).
That’s fine for your website, but what about all the rest of those top 30,000 sites you don’t control? Well, you could email the developers, let them know that their site isn’t working in the most popular mobile web browser; let them know that you can’t use their service. If you’re a programmer or web developer you can help out with Mozilla developer Christian Hellman’s effort to Pre-fix the web. Pre-fix the web is looking for developers willing to seek out projects on Github that only work in Webkit and then fork the project, adding the missing prefixes to the CSS, extending JS code to do proper feature detection and then sending a pull request. In other words, literally fixing the web.
We at Webmonkey hope it’s obvious that building WebKit-only sites is a waste of time. If you’re only interested in iOS users then take a tip from Instagram and build a native app. As Peter Linss, Hewlett-Packard’s CSS WG representative says the CSS WG minutes, “there’s no advantage to the Web to have someone write a platform-specific website.” There’s also no real advantage for the developer, especially when an automated prefixer can do all the work for you. If you want your site to embrace the web, take the time to learn the craft and embrace all of the web. Be good at what you do and do it right.
