using ems for background image

Hi,

Our CMS has the functionality to increase the size of text images etc. for accessability.
I need to set the height and width of images in the CSS and it works fine with the new stylesheet. If I don't or use px instead of ems then everything else increases in size but the element does not.

The problem is I want to set a background image and when I press the increase size button everything increases however the background image does not scale because I cannot set the background width and height in ems.

Any suggestions?

regards,

Unfortunately, unless your using CSS3 and a compliant browser, your not going to be able to resize the background image via CSS.

Your best bet would be to use javascript or jquery to resize the background.
