There is something like this:
<div id="block1" style="width: 300px; height: 300px; background-color: red;"> <div id="block2" style="width: 300px; height: 150px; background-color: #000; color: #fff; opacity: 0.2;"> <div id="block3" style="opacity: 1;"> test test test </div> </div> </div>
Here is the implementation on jsfiddle - http://jsfiddle.net/U5CLR/
How to remove the opacity (or rather return it to the value 1) for the block # block3?
Thank.
