add to cart button in CSS

for the life of me, I can't seem to change the size of the 'add to cart' button.
I'm experimenting with the css buttons.

I changed the default to

 .button_in_cart{width:30em;}

and it does nothing. I tried setting it in pixels, I tried all sorts of sizes.. no luck.

If I look in firefox web developer, there is nothing setting the width other than that. It shows accurately whatever I've set .buttin_in_cart to

I tried adding padding-left and padding-right, it seems to have no effect.
I then looked at the #cartAdd box, which is its parent, and made it bigger. No luck.
Can someone figure this out?

What am I missing?

That did it. Damn, so easy. Why couldn't I find that post?

And.. why does it only work on the one button, and why wasn't it fixed?

anyways, thanks for the quick find.

I am trying to make my add to cart button larger also, where you able just to change add to cart, or did you have to change all the buttons? If you did add to cart only, can you elaborate on how you did it?
