Status: RESOLVED DUPLICATE of bug 215083

(Core :: CSS Parsing and Computation, enhancement)

Description

[Pierre Rudloff]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en; rv:1.9.2.14pre) Gecko/20101214 Camino/2.1a1pre (like Firefox/3.6.14pre)

Opera seems to be the only browser to support this kind of code :
img#myImage:hover{
   content:url('myImage.png');
}

I don't know if it is part of the spec but I could be quite useful to dynamically change an image without using JavaScript.

Reproducible: Always

Actual Results:  
Nothing.

Expected Results:  
The image is replaced by another one.

It's not in the current specs, no.  There have been some proposals for a CSS3 Generated Content module that might have allowed doing this, but they seem to have been abandoned.
