jquery UI button too width although padding = 0
===

I try to reduce the width of some of my jQuery buttons. I use the following code to remove the padding, but there are still at least 5 pixels to the left and right of the text in my button.

    .button().css({ 'padding-left':'0px', 'padding-right':'0px' });

When I change the '0px' to '200px' for example I end up with a really width button, so the code should be correct in general and target the right element.
