The default form submit button looks ugly on almost any website. Wouldn’t it be nice to be able to style it to fit in with your design?
Even better, how about adding a hover effect to make it clear that clicking on it does something?
After a bit of searching, I’ve found the solution at www.digital-web.com – using the <button> tag. With the addition of some javascript to cope with IE’s lack of support for the :hover pseudo class, you can even have hover effects.
