WordPress-style Buttons
=======================
Create a button by adding the `.button` class to an element. For backwards
compatibility, we support several other classes (such as `.button-secondary`),
but these will *not* work with the stackable classes described below.

Button Styles
-------------
To display a primary button style, add the `.button-primary` class to a button.

Button Sizes
------------
Adjust a button's size by adding the `.button-large` or `.button-small` class.

Button States
-------------
Lock the state of a button by adding the name of the pseudoclass as
an actual class (e.g. `.hover` for `:hover`).
