Sidebar not showing IE8 / White bg instead of gradient

[polyfragmented]

Koen,

I am pretty much sure that the IE8 background problem doesn't stem from a background image, because you don't have one set for the wrapper (which stays white in IE 8). Instead, you've set the background color a bit transparent with

Code:

background-color: rgba(255, 255, 255, 0.746094);

so the background-image shows through.

When I check out the CSS for the wrapper in IE 8 (actually using IE 9, but set the rendering to IE 8), the development tools show me

Code:

background-color: rgb(255, 255, 255);

Have you set some background color fallback for IE below 9, because it seems that IE8 doesn't support rgba().

I don't have the time right now to check out your CSS further, but I bet it's got to do with rgba(). Check out this older article in which proprietary CSS filters are being used to coax IE into submission. Maybe you can use that to make it work.

Good luck!
