Which border radius property will work in IE9?

Question

In IE9, which border radius property will work?

 border-radius:20px
-webkit-border-radius: 20px;
-moz-border-radius: 20px;

border-radius:20px or ms-border-radius:20px

Answer 1

IE9 will support border-radius see: http://ie.microsoft.com/testdrive/HTML5/01BorderRadius/Default.html

Answer 2

border-radius will work. In fact MS made a big deal about how they're the only browser that actually supports the 'standards' while all the other vendors uses specific prefixes.

/me rolls eyes.

Answer 3

If you're reading this page then may also wish to consider include khtml-border-radius for compliance with Konqueror so it looks like:

 -khtml-border-radius: 20px;
 -moz-border-radius: 20px;
 -webkit-border-radius: 20px;
 border-radius:20px;
