与X-UA兼容的版本：IE = Edge和IE = 100之间的差异

Question

Some features of one of my web applications is not working properly for some users in internet explorer 9, though I have made it compatible for IE 9. After doing some investigation I found the problem will happen if IE9 opens the site with document mode IE7.

To get rid of the problem I instantly used the following meta tag to force the browser to use its latest engine all the time to open this site.

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

I found another option to use this meta with content='IE=100'.

As most of my problems were css related, which option will have the minimum impact on other browser scripts?

Answer 1

See Understanding legacy document modes in Specifying legacy document modes :

Starting with IE11, edge mode is considered the preferred document mode. (In earlier versions, it was considered experimental.)

[...]

Starting with Internet Explorer 11, content values greater than "10" lead to edge mode, which is the highest version supported by the version of Internet Explorer used to view the webpage.
