For IE8 and above, for example:

The code is as follows:

<meta http-equiv="X-UA-Compatible" content="IE=9; IE=8; IE=7" />

Force the browser to render according to a specific version standard. But it does not support IE7 and below versions. If separated by a semicolon (;), there will be different compatibility for different browser versions. For example,

<meta http-equiv="X-UA-Compatible" content="IE=7; IE=9" />

The above shows that IE8 and IE7 will be rendered according to the IE7 standard, but IE9 will still follow the IE9 standard. render. It allows for different backward compatibility levels. Although in a real situation, you only need to choose one version:

<meta http-equiv="X-UA-Compatible" content="IE=8" />

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8" />

<meta http-equiv="X-UA-Compatible" content="IE=Edge" />

, this means that the browser will be forced to render according to the latest standards. Just like using the latest version of

on Google’s CDN, this is to follow the latest version, but it may also break your layout because there is no fixed version. Finally, consider the following

<meta http-equiv="X-UA-Compatible" content="IE=Edge,chrome=1" />

For more information, there is plenty to read here, and if you want to learn about ChromeFrame (which I recommend) you can learn about its implementation here.

<meta http-equiv=”X-UA-Compatible” content=”IE=7″ /></p>< p><meta http-equiv=”X-UA-Compatible” content=”IE=EmulateIE7″ ></p>< p><meta http-equiv=”X-UA-Compatible” content=”IE=EmulateIE8″ >

But still is the first choice.
