With IE8 Beta 2, Microsoft announced a brand new feature known as Compatibility View. In a nutshell, Compatibility View allows content designed for older web browsers to still work well in Internet Explorer 8.
Compatibility View and End Users: When a web site says that it supports modern web standards, Internet Explorer 8 respects that and displays the site using its most standards compliant mechanism. In the majority of cases, this works out just fine. However, every once in a while, a page that says “display me using modern standards” really means “display me like Internet Explorer 7 used to display modern standards pages”. This is where Compatibility View comes in.
There are a bunch of changes under the hood, but the main points to know are –
- Sites on the public internet still display in IE8 Standards Mode by default.
- Switching in and out of Compatibility View (between IE7 and IE8 modes) happens on the fly without a browser restart.
- Compatibility View is domain specific.
A new UI button located in the navigation bar just to the right of the address bar (next to the refresh button) controls the Compatibility View feature and replaces the Emulate IE7 button from Beta 1.
