Working with CSS layouts can save you time and money. Once you got familiarized with its principles of functioning, CSS is easy to use and much better than tables, at least when it comes to later changes of your web page. Addressed mainly to beginners, but not only to them, the following resources can be of good help:
1. The Leslie Franke CSS cheat sheet: syntax, selectors, pseudoselectors, units, properties and values, everything gathered on only one page.
2. I love Jack Daniels CSS cheat sheet: all CSS elements explained. It includes a visual example of the box model, unit reference for CSS units and the various media types CSS makes allowance for.
3. Brett Merkey’s CSS cheat sheet: basic concepts, units, cascade, properties, pseudo-classes and pseudo-elements, all of these clearly explained with examples.
4. Tek271’s CSS cheat sheet: not so detailed as other cheat sheets, but still useful, with good information.
5. Apple’s CSS cheat sheet: freeware dashboard widget for Mac, displaying the essential information from the CSS cheat sheet.
