Hi,

Can someone explain me how I can do calculations with padding.

I have something like elt.style.padding = "6px";

Now I want to calculate the size for a containing element. Something like:
container.style.width = 100 + (2 * elt.style.padding) + ""px";
This formula is accepted in Mozilla but crashes with IE.

I could of course get the padding of the elt, look if it contained px or em
or nothing as unitsize, strip the unit, etc. But I suppose that there must
be some function that can handle this for me.

Thanks,

Wim
