The popular tag is IE8
Browser manufacturers are rushing to release version updates
Some web pages also have compatibility issues with IE8
A simple line of code allows IE8 to automatically call IE7's rendering mode
Just add the following HTTP meta-tag to the page:
<meta http-equiv=X-UA-Compatible content=IE=EmulateIE7 />
As long as IE8 reads this tag, it will automatically start IE7 compatibility mode to ensure the complete display of the page.
