I don't get it, what makes IE smoothen your page
 

When i make a site in wordpress it's smooth in firefox and IE.

But now I'm making a site pretty much from the ground up and everything is pixelated in IE unlike any other site in IE. I don't get it :helpme

compatibility mode ?

that's right, but i didnt understand the way WP makes it work... I have added this line now and it works:
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"></meta>

But in WP sites it's made like this:
<!--[if ie]><meta content='IE=edge,chrome=1' http-equiv='X-UA-Compatible'/><![endif]-->

When I add it like this in the site im working on it doesn't work. Is it because the brackets call a function that's standard in WP? (as you can see im definitely not a programmer)
