Some Awesomeness from the Folks at the W3C

Dynamic outlines: the 'outline' property

The 'outline-color' accepts all colors, as well as the keyword 'invert'. 

'Invert' is expected to perform a color inversion on the pixels on the screen. 

This is a common trick to ensure the focus border is visible, regardless of color background.

  1. Outlines do not take up space.
  2. Outlines may be non-rectangular.
Outlines have been around since CSS2.1, but hadn't heard about them.

Enjoy!
