I think that it's your case, because let's face it 99.9999999999999999999% web pages do not specify any compatibility mode :-) If no X-UA-Compatible meta tag is found, the browser renders the page with the newest engine, UNLESS you explicitly chose to load it in compatibility mode.It may be useful if you want to display a page as if it were Internet Explorer 5.5, by specifying (IE=Emulate7), since IE7 compatibility mode made it possible to display old legacy pages designed for IE 5.5 The difference from the standards mode is that here you basically tell him to use the compatibility engine of that version.

This instruction is for displaying the page with the compatibility mode of the given browser. Checks if the content of this meta-tag is something like, agian, where "X" is either 7, 8, 9.When a page includes this meta it instructs IE to display it with the standards mode of the given browser version, which means that it will use the standard engine of that version. Checks if there is the meta-tag in the header of the page:, where "X" is either 7, 8, or 9.But before, IE more or less follows the given flow: Basically, IE attempts to find the best compatibility mode first before rendering the page with the newest version of its engine, IE10 in your case.
