https://developer.mozilla.org/en/docs/Web/CSS/box-shadow

box-shadow: [inset?] [top] [left] [blur] [size] [color];

Tips:

- We're setting all the blurs to 0 since we want a solid fill.

- Add the inset keyword so the box-shadow is on the inside of the element

- Animating the inset shadow on hover looks like the element is filling in from whatever side you specify ([top] and [left] accept negative values to become [bottom] and [right])

- Multiple shadows can be stacked

- If you're animating multiple shadows, be sure to keep the same number of shadows so the animation is smooth. Otherwise, you'll get something choppy.
