// LESS Prefixer

//
// All of the CSS3 fun, none of the prefixes!
//
// As a rule, you can use the CSS properties you
// would expect just by adding a '.':
//
// box-shadow => .box-shadow(@args)
//
// Also, when shorthand is available, arguments are
// not parameterized. Learn CSS, not LESS Prefixer.
