Here is a small sample of the available styles for a button. There are four different sizes, three different options for corner rounding and complete color customization.
You can obviously add a link to a button. However, the button stack has been integrated with many other Foundation components. You can submit or reset a Foundation Form, launch a Reveal lightbox and open a Dropdown. You can even use it as a generic button that can be placed into your favorite stacks like Expose or Peek-a-Boo.
