Ajax EDD add-to-cart items

This is a screenshot of some of the CSS elements before implementing the AJAX functionality on my Easy Digital Downloads add-to-cart button. Screenshot taken in Chrome on MacBook Retina.

Basically, you've got the "Buy Jump Start" button with the price on it. When you click it, the loader fades in over the price. Then, the button is replaced with the yellow "Checkout" button as the black success prompt fades/slides in, and then disappears.
