Internet Explorer 8 has arrived… Is your site ready?
Here are some useful links to check your sites compatibility with IE8.
The short answer is to run your site in IE8 compatibility mode described in the link below.
A quick fix is to add a meta tag on any page which you want to render as version 7 or below.<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />
Upgrading your site to run in IE8 Standards Mode is the best option in the long run, but in the interim you can quickly fix these types of issues by running your site in Compatibility Mode. This is described in Jefferson’s post on the EmulateIE7 meta tag.
And one thing that hasn’t changed much over the past several months is the fact that many Web sites still aren’t compatible with IE 8. The Compatibility View list includes some major sites Apple.com, CNN.com, eBay, Facebook, Google.com, NYTimes.com, even Microsoft.com (!)
Now, if you are rendering in IE5/IE7 mode, then Nothing changes except that there will be a few methods added that shouldn’t interfere with your page. However, if like the majority, you are running with a doctype set, and thus in IE8 Standards mode, the following changes have occurred.
If best practices are followed in development, the default appearance and behavior of a Web site viewed in Internet Explorer 8 should be the same as in Internet Explorer 7. By default, however, Internet Explorer 8 uses a more compliant Standards mode that supports the latest feature set in the CSS 2.1 specification.
