IE =边缘告诉Internet Explorer使用该版本的IE可用的最高模式。 Internet Explorer 8可以支持多达IE8模式，IE9可以支持IE9模式等等。

但是 chrome = 1 tag？

解决方案

这是Google的Chrome Frame 浏览器插件。

ChromeFrame可以安装在各种版本的IE浏览器中（尤其适合老年人使用版本与现代网络功能无法很好地发挥作用）。它本质上是在IE浏览器内运行chrome浏览器。

对于meta标签，IE应该运行在标准模式（最新版本边缘） - 如果存在，则激活chrome帧。

我通常为IE的旧版本做一些条件浏览器，允许用户安装插件作为选项。

I just saw this meta tag in the wild and was wondering it does and why it's used?

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

Reading the documentation on About.com, it says:

"IE=edge" tells Internet Explorer to use the highest mode available to that version of IE. Internet Explorer 8 can support up to IE8 modes, IE9 can support IE9 modes and so on.

But what about the chrome=1 tag?

解决方案

It's for Google's Chrome Frame browser add-on.

ChromeFrame can be installed on various versions of IE (especially handy for older versions that don't play nicely with modern web features). It essentially runs the chrome browser inside of IE.

In the case of the meta tag, IE should run in standards mode (most current edition "Edge") - and activate chrome frames if it exists.

I usually do some conditional browser stuff for older versions of IE, allowing the user to install the add-on as an option.
