CSS changes on the category page

Hello

I need to do minor changes on a few controls, for example increase the width of a button cause when I change language the text is larger than the button's width.

When I click on one of my categories the browser takes me to

http://www.mystore.com/category/4--.aspx?orderby=0

which is this page in the nopCommerce project? I thought of doing the changes through VS 2008.

Unless I can find the solution through a css file.

Thanks

Look at Category.aspx file and \Templates\Categories\ directory

Thanks, the button I was looking for was in the ProductBox1.ascx file.
