My personal guidelines: * Partition into sections for fonts, colors+images, positions+spacing, text, and specials. * Refactor for minimal property duplication, instead of selectors. For example text-weight:bold; will be mentioned only once, but the "#content a" selector multiple times. * Use a CSS reset. * Make an extra file per browser+version for hacks. Do not use hacks, which make sure they get triggered in IE7, but not 6 or 8, for example, but use ie6.css, ie7.css, and ie8.css. Duplicate code for this if necessary.
