Optimising Style Sheets for the Web

Make sure your style sheets are accessible for people with disabilies

Faster Style Sheets:

Use valid CSS (validate it)
Use an external style for all repetitive formatting
Use style sheet shorthand, eg. {margin: 0px} rather than { margin-top: 0px; margin-left: 0px etc }
Where possible, define styles globally in the <body> tag
Create pages that still function when style sheets are turned off (W3C Checkpoint 6.1 (Priority 1))
