try to declare IE coding

hope this help :-)

Ali Hussain answers:

This is due to the browsers being old.

You have a few options

1) You will need to write a separate css for the ie browser fixing the issues
2) Use HTML5Shiv
3) For border-radius you will need to use PIE.htc

All css fixes

Andrew Wong answers:

Try to add these few lines on the header:

<meta http-equiv="X-UA-Compatible" content="IE=EDGE" />
<!--[if lt IE 7]><script src="http://ie7-js.googlecode.com/svn/version/2.1(beta4)/IE7.js"></script><![endif]-->
<!--[if lt IE 8]><script src="http://ie7-js.googlecode.com/svn/version/2.1(beta4)/IE8.js"></script><![endif]-->
<!--[if lt IE 9]><script src="http://html5shim.googlecode.com/svn/trunk/html5.js"></script><![endif]-->

That should help you go through some old IE.

Hi Steve,

Here's a few resources to get you started:

http://fetchak.com/ie-css3/
http://ie.microsoft.com/testdrive/HTML5/BorderRadius/
http://jjis.me/a/912 - A good method using SVG.

You could of course use <em>polyfills</em> along with Modernizr. Here's a good list of resources:

Also, as Daniel said before, don't forget to declare your IE coding is IE9.
In fact, all already stated solutions are also valid, especially CSS3 Pie:
