Support for “border-radius” in IE

Question

Does anyone know if/when Internet Explorer will support the "border-radius" CSS attribute?

Answer 1

While you're waiting.. Curved corner (border-radius) cross browser

Answer 2

Use -ms-border-radius: 15px, any element that uses css -ms- is compatible with IE.

Answer 3

A workaround and a handy tool:

CSS3Pie uses .htc files and the behavior property to implement CSS3 into IE 6 - 8.

Modernizr is a bit of javascript that will put classes on your html element, allowing you to serve different style definitions to different browsers based on their capabilities.

Obviously, these both add more overhead, but with IE9 due to only run on Vista/7 we might be stuck for quite awhile. As of August 2010 Windows XP still accounts for 48% of web client OSes.

Answer 4

SOLVED - not rendering border radius correctly in IE 10 and 11

For those not getting the -ms-border-radius: or the border-radius: to work in IE 10,11 And it renders all square then follow these steps:

1. Click on the gear wheel at the top right of the IE browser
2. Click on Compatibility view settings
3. Now uncheck the 2 boxes that are checked by default.

Answer 5

Yes! When IE9 is released in Jan 2011.

Let's say you want an even 15px on all four sides:

.myclass {
 border-style: solid;
 border-width: 2px;
 -moz-border-radius: 15px;
 -webkit-border-radius: 15px;
 border-radius: 15px;
}

IE9 will use the default border-radius, so just make sure you include that in all your styles calling a border radius. Then your site will be ready for IE9.

-moz-border-radius is for Firefox, -webkit-border-radius is for Safari and Chrome.

Furthermore: don't forget to declare your IE coding is ie9:

<meta http-equiv="X-UA-Compatible" content="IE=9" />

Some lazy developers have <meta http-equiv="X-UA-Compatible" content="IE=7" />. If that tag exists, border-radius will never work in IE.
