Hummmm, yes I see now that Flanagan regards them as read-only. I'll
have to rethink that aspect.

Umm no. If I take as a specific example the left padding of a <div>,
then I was assuming that if I had:
.mystyle { padding-left: 2px;}
and that this was applied to a div with id="xyz", I could read the
value by just doing:
pad = parseInt (document.getElementById("xyz").style.paddingLeft);
but it seems not. I can apparently only do that by first explicitly
setting it:
document.getElementById("xyz").style.paddingLeft = pad + "px";
But why can I not read it as above?
