CSS difine a class with another class

[irate]

Is it possible to create a class that is simply one or more other classes with added attribures.

Eg.

If I had the following classes in a generic style sheet:

.bgcBlack                { background-color: #000000; }
.fgcWhite                { color:            #FFFFFF; }
.ffMonospace             { font-family:    monospace; }

and then on a particular HTML page I wanted a class that combined the above classes and made the font size 20px, I know I COULD do the following:

<span class=&quot;bcgBlack fgcWhite ffMonospace&quot; style=&quot;font-size:20px;&quot;>
 this is the text
</span>

but I would prefer to create a new class something along the lines of:

.newClass             {bcgBlack;fgcWhite;ffMonospace;font-size:20px;}

So, is this possible, and if so what is the syntax.
Thanks in advance.

I think the best you could do would be:

.bgcBlack, .newClass    { background-color: #000000; }
.fgcWhite, .newClass    { color: #FFFFFF; }
.ffMonospace, .newClass { font-family: monospace; }
.newClass               {font-size: 20px;}
