Hopefully quite a simple one...
I have an image (radial gradient) which is absolutely positioned top left and is 300px x 300px
I'd like to stretch the image to half the browser window (keeping aspect ratio if poss).
Something as simple as <img src=gradient.jpg width=150%> works in IE but not in mozilla. It also doesn't size to exactly half.
What's the best way to implement something like this? (if i need to use js that's fine)
