Below is my code to round the top two corners of a header using css. IE is driving me nuts. My page looks fine on all other browsers. I thought that curved corners are supported on IE9
<style type="text/css">
#header {
height: 70px;
font-size: 2em;
color: #fff;
padding: 40px 0 0 40px;
background: #0B3A68 no-repeat 15px 11px;
position: relative;
font-style: italic;
font-family: Arial;
border-top-left-radius: 40px;
border-top-right-radius: 40px;
}
</style>
<div id ="header">
test
</div>
