I am doing work for a client who forces compatibility mode on all intranet sites. I was wondering if there is a tag I can put into my HTML that forces compatibility mode off
This is due to the setting within IE Compatibility settings which says that all Intranet sites should run in compatibility mode. You can untick this via a group policy (or just plain unticking it in IE), or you can set the following:
Apparently it is not possible to change the compatibility view settings as a group policy but it is something that can perhaps be changed in the registry, this meta tag works fine for me, I had to make the required attribute work as part of a html form, it worked in chrome and firefox but not IE.
Here is a nice visual of what browsers support each individual html 5 element.

Notice the one common denominator Google Chrome, it supports everything. Hope this is of help
