Only in extreme cases where it's the only appropriate thing to do, as a
JavaScript developer, will I even consider making stylesheet changes via the
DOM.  Getting scripts to work cross browser on that front is incredibly
painful.  PPK took a shot at it a while back, and had to resort to using an
"ugly kludge".

This page is a good highlight of the problems involved, though:

It's possible that this is going outside of the scope of this working group,
but for even the simplest DHTML work, the style property is essential.

I agree, though, that the style attribute isn't conforming, and even if it
were, the JavaScript style property would be infinitely more useful simply
returning computed styles, rather than the value of the style attribute.
However, that raises a problem with implementation logistics when setting
style rules (i.e. what are you setting, if not the inline style?) for an
element, which may or may not have an id attribute.

I haven't got a solution to propose here, but making changes to the
stylesheet itself isn't a solution so far as I'm concerned for the problem
of changing styles on specific elements via JavaScript.
