CSS Reference (Mozilla Developer Network)

This CSS Reference lists all standard CSS properties, pseudo-classes and pseudo-elements, @-rules, units, and selectors in alphabetic order. It allows you to quickly access detailed information for each of them. It not only lists the CSS 1 and CSS 2.1 properties, but also is a CSS3 reference that links to any CSS3 property and concept standardized, or already stabilized.

What can you do more of that makes a difference, shifts the balance, has an impact, adds beauty, changes the status quo, creates something worth being created, improves life, moves things forward, reduces waste, engages people, or allows love?
