IE 兼容性元标记之间的区别

Difference between IE compatibility meta tags

到底有什么区别:

<meta http-equiv="X-UA-Compatible" content="IE=11">

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE11">

?

如果您在您最喜欢的搜索引擎中输入 MSDN X-UA-Compatible,您会找到 official documentation,上面写着:

 X-UA-Compatible value | Document modes
 ----------------------+---------------------------------------------------------
 E=11                  | IE11 mode
 IE=EmulateIE11        | IE11 mode (if a valid <!DOCTYPE> declaration is present)
                       | Quirks Mode (otherwise)
