Can you overlay a transparent css3 gradient over a

问题:

I'm trying to put a css3 gradient over the top of a background image. Using the code below puts a background image on top of my gradient, but i'm trying to do it the other way around, so the gradient acts as a mask on top.

url(images/darkwood.png),
-webkit-gradient(linear, 0 0, 0 100%, from(#EEF), to(#000)) 300px 50px no-repeat,
-webkit-gradient(linear, 0 0, 0 100%, from(#EFE), to(#000)) 0 0 no-repeat;
background: 
url(images/darkwood.png),
-moz-linear-gradient(#EEF, rgba(0,0,0,1)) 300px 50px no-repeat, 
-moz-linear-gradient(#EFE, rgba(0,0,0,1)) 0 0 no-repeat;

Thanks for your help

The example from this answer won't work with resizeable divs.

Your code would work fine. But as I understand it, CSS reads from the right to the left. So you would have to use the following:

div {
    background: -webkit-radial-gradient(top center, ellipse cover, rgba(255,255,255,0.2) 0%,rgba(0,0,0,0.5) 100%), url('http://www.google.co.uk/logos/classicplus.png') repeat;
}
