why is this page triggering compatibility mode in ie?

Question

The markup is valid, I've been trying for a couple of hours by now, but I still fall in compatibility mode, on both IE8 and IE9..any hint would be great..

here's the link to the page

P.S. I've already tried adding

<meta http-equiv=“X-UA-Compatible” content=“IE=8” />

etc etc

Answer 1

After some other testing, I discovered that there was a CSS property that was triggering the compatibility view. exactly max-width.

Answer 2

My IE9 is in IE9 Standards mode. Check you have turned Compatibility View off. When you click on it manually, IE remembers that even after restart.

You have to declare content="IE=9" in order to force IE9 Standards mode.
