Disable filter in IE9

Hi,

I want to disable the filter gradient in IE9.

I tried this:

html[data-sap-ui-browser='ie9'] {filter: "progid:DXImageTransform.Microsoft.gradient(enabled = false) !important";}

This is removing the gradient, But, I have backgroung image in body and the background image has still has the gradient.

How can I remove the gradient from background image in body.

Thanks,

Shashi
