Microsoft Offers Guide to Adapting Your Site for IE 10
Microsoft’s Windows Phone 8 offers much better HTML5 support than its predecessors thanks to the Internet Explorer 10 web browser.
Unfortunately, if you’ve been building WebKit-centric sites IE 10 users won’t be able to properly view your site, which is why Microsoft has published a guide to adapting your WebKit-optimized site for Internet Explorer 10.
If you’ve been following CSS best practices, using prefixes for all major browsers, along with the unprefixed properties in your code, then there’s not much to be learned from Microsoft’s guide (though there are a couple of differences in touch APIs that are worth looking over).
But if you’ve been targeting WebKit alone, Microsoft’s guide will get your sites working in IE 10, WebKit, and other browsers that have dropped prefixes for standardized CSS properties.
Sadly, even some the largest sites on the web are coding exclusively for WebKit browsers like Chrome, Safari and Mobile Safari. The problem is bad enough that Microsoft, Mozilla and Opera 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. So far Microsoft hasn’t carried through and actually added support for
-webkit to any versions of IE 10, but Opera has added it to its desktop and mobile browsers.
Microsoft’s guide to making sites work in IE 10 for Windows Phone 8 also covers device detection (though it cautions that feature detection is the better way to go) and how to make sure you trigger standards mode in your testing environment, since IE 10 defaults to backward-compatibility mode when used on local intranets.
