CSSBattle at CSS Café

CSSBattle is a code-golfing game: replicate the given patterns with just HTML and CSS, the shortest code wins.
Gunnar will reveal some magic tricks to do so. (Keep your expectations low: he’s not gonna take you into the top ten. 😜) Some of which you would never use in production code, while others might prove useful.
Warning: this game is addictive.
