IE not recognizing border-radius, but only on our site

Here’s the test page with a basic border-radius element. [URL=“”]Here is the same exact code hosted elsewhere.

On IE 11, the test box simply doesn’t have rounded corners… but shows rounded edges, with the same exact code, on other sites just fine.

The IE code inspector here shows that it’s just not even recognizing border-radius as a legitimate attribute - but again, only for our site.

Any idea why this is happening?

If this line exists on your site:

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

change it to this

<meta http-equiv="X-UA-Compatible" content="IE=edge">

As Ron said you are using the ie8 meta tag which makes ie8 + all behave like ie8 and is a very bad thing to do unless you have specific script only written to work in IE8. You lose all the benefits of any new css and much better behaviours in ie9+.

If you use the ‘edge’ meta tag as Ron suggests then IE will always render the page in standards mode (avoiding people clicking the compatibility button by mistake) and will render as the browser version that is being used (e,g, IE8 renders as IE8, IE9 renders as IE9, IE10 renders as IE10 and so on…).
