Hi guys,  
I’d like to find out that whether if it’s possible to call a css class within another css class.  
For instance, I’ve declared a class called ‘linktxt’ which will be applied to a link. I have also declared another class for an image called ‘bg’. When I rollover the link, bg should change from one image to the other.

```auto

.bg{
	background-image: url(images/arrow.gif);
}

.linktxt a:hover{
            <!-- Background image of the .bg class changes to url(images/arrow_over.gif) -->
}

```

Any idea how I should come about doing that?
