Vantage Theme – Button CSS

Hello,

I absolutely love this theme, however I do not like the buttons that are defaulted in for the submit button on forms and other things. Is there any way to change this? I went looking through the style.css to see about changing it but I could not find the right code.

Any assistance would be helpful. You can see a sample of the submit button the page.
