Today we are glad to release two useful cheat sheets that will help you quickly look up the right CSS 2.1-property or an obscure CSS 3 property. The style sheets contain most important properties, explanations and keywords for each property. We’ve kept CSS2 and CSS3 on separate Help Sheets for now as not everything in CSS3 is finalised, or works in all browsers (cough, IE).
The CSS 2.1 Help Sheet covers Syntax, Font, Text, Margins, Padding, Border, Position, Background, List, Media Types and Keywords. The CSS 3 Help Sheet contains code snippets for Rounded Corners, Box Shadow, Multiple Columns, Text Shadow, RGBa, Font Face (actually, not the CSS3 property, but still include for the sake of usefulness), Box Sizing, Box Resize, Outline and Gradients.
