calculation with padding

[Wim Roffal]

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

In CSS, you can't.

If this is important, create your files as input to some
preprocessor that writes valid CSS as output. (This is what I do, in
fact, to get margins all equal when the text sizes are different.)
