[html] Is it still valid to use IE=edge,chrome=1?

I read Chrome Frame closed last month, I thus tried to understand what it'd mean for the X-UA tag and after 3 hours of research I still didn't find the answer I'm looking for, my question is the following :

Is it still valid nowdays to use IE=edge,chrome=1 or should I stop at IE-edge from now on ? Or what would be the best pratice to do regarding X-UA, should it be avoided ?

The answer is


<head>
<meta http-equiv='X-UA-Compatible' content='IE=edge'>

worked for me, to force IE to "snap out of compatibility mode" (so to speak), BUT that meta statement must appear IMMEDIATELY after the <head>, or it won't work!


It's still valid to use IE=edge,chrome=1.

But, since the chrome frame project has been wound down the chrome=1 part is redundant for browsers that don't already have the chrome frame plug in installed.

I use the following for correctness nowadays

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