i work for a company where all our sites currently use the XHTML 1.0 transitional doctype (yes i know it is very old school). I want to change them all to use the HTML5 doctype seeing as it is backwards compatible. One of the reasons why i want to make the switch is because in IE8 if someone has the developer tools installed then the old XHTML doctype switches the browser into compatibility mode and renders the page as IE7. From reading up on it i was led to believe that the HTML5 doctype will set any page to render in standards mode, but this is not happening when i test it on our staging server it still flips into IE7 rendering mode.
The weird thing is if i save the page with HTML5 doctype locally and open it, it is rendering in IE8 standards mode. There must be something else causing it to drop into compatibility IE7 rendering. Any ideas what this could be?
Below is the head of the test page i have been looking at:
