$("#myElem").css('color', '#ff0000');
It would probably be better if 'cat_[id]' is the element's ID rather
than a CLASS, provided that it's unique in the whole document:
<div id="cat_12">...</div>
Using that, you can easily update a whole set of 'cat_[id]' in one
call (if that's what you want to do):
$("[id^=cat_]").css('color', '#ff0000');
This will update every element with IDs that begin with 'cat_'.
Theoretically you can do that with CLASS also, but when the CLASS
attribute also allows definition of multiple classes, such as:
class="header cat_45"
in which case would require a bit more work to locate because it would
not fall in the criteria of "begins with cat_" anymore.
