IE8 is here.

Windows Internet Explorer 8 is here. This is the first launch of IE that I’ve been excited about in a long time. Why? With full support for CSS 2.1, it’s now a standards-compliant browser. (It also supports CSS 3.0 in a limited capacity.) Sure, it’s now one more browser to account for, but if your site works properly in newer versions Firefox, Safari, Chrome, Opera, etc… chances are it will work in IE8. If you’re unsure of how to fix any issues your site might have in Internet Explorer 8, but it works fine in previous versions, forcing legacy rendering is as easy as adding a meta tag:

[html]

[/html]

OR, on a per-site basis, add the HTTP header: X-UA-Compatible: IE=EmulateIE7
