HTML5, CSS3 and You!

So, how is your personal relationship to HTML5 and CSS3 going? Did you even know that you had one? You do now or soon will, if your library continues to rely on Windows XP for staff or patron workstations.

Perhaps we should start with the basics. What are HTML5 and CSS3? Technically, these are website content format standards that are maturing but are still under development. They represent a large number of feature enhancements over HTML4 and CSS2; too many to get into here, and probably you don't need (or want) to care about all the details.

What's important for you to understand is that some of these new features are highly, highly desirable to website developers. This is why Google Apps (among other sites) ended their support for Internet Explorer 6 in 2010, and then ended their support for IE7 (and Firefox 3.x and other browsers) in 2011. Can you guess the fate of IE8? Hot tip: don't bet on its longevity...

Officially, Microsoft is continuing to support Windows XP SP3 and IE8 until April 8, 2014. However, there will be no new versions of IE for the XP platform; IE8 is all you get. The good news is that IE8 does support some HTML5 features. The bad news is that some sites have already dropped support for IE8 because its implementation of HTML5/CSS3 is just too primitive or incomplete.

The world is not ending, of course, at least not on account of IE8. If your budget says that XP stations will be operating in your library for some time to come, then there is always Firefox. SCLS will continue to update Firefox on XP stations for as long as we are able to, and Firefox on XP is fully capable of handling websites that demand a lot from HTML5 and CSS3. You just need to be aware that as time goes on, IE8 will become less and less useful (and in some cases impossible to use) on evolving websites.

Want to know more about what's missing from IE8 (and for that matter, from IE9 on Windows 7)? Check out the fun interactive chart at http://html5readiness.com/. Hover your mouse pointer over any spoke on the chart wheel to see the name of the new feature that it represents, and note how many spokes are missing labels indicating IE8 and IE9 support. Want to replay the "browser wars" of recent years? Dial back the chart to yesteryear by clicking on the tags above it.
