There are no negative effects to applying multiple classes to a single
element. The only problem is when you try to style an element that matches
two (or more) classnames, e.g.:
#content .primary.highlighted {
background: #ff0;
}
That will work in Firefox/Safari, and apply the rule to any element with
both the "primary" and "highlighted" classes; but in IE6 it doesn't work, it
will just see it as .highlighted.
