10. Pairing Fonts
1. Fonts in a family pair well Like: Droid Sans and Droid Serif
2. They're clean and modern, plus (as you'd expect) they're
well suited for the web and smaller devices on account of
their large x-height.
3. The x-height of a font describes the height from the base
line to the upper reaches of the lower case characters,
like the x. A proportionately large x-height helps with
readability. And these two both share that quality.
