Thanks! That looks to be just the solution I'm looking for.

I don't think jQuery is designed to get an attribute from a class.
The code you wrote


...
var color = $(".myclass").css("background-color");

works by pulling the background color from the DOM object.  A
different hack that would work in one line:

$('').addClass('myclass').css('background-color');

That would create a div, add a class to it, and fetch the background
color.

You could access the CSS rules via document.stylesheets[x].cssRules
[x].style.color, for example, but cross-browser support is not very
good:

I don't think there's anyway to directly reference what's in a style
declaration, only indirectly through an html element (as you found).
However, you could temporarily create an element, assign the class of
interest to it, and work with that.  Of course, you probably want to
'learn' what classes are defined so you know what to assign to the
temp element, which gets you nowhere because there's no way to read
the style information (that I know of).
