I have posted a large update to my SharePoint 2007 CSS reference chart. In addition to adding some new styles and tips, I have added "Copy to Clipboard" functionality that will copy the CSS source code for the given style to your clipboard, so you don't have to chase down styles by looking up line numbers. Instead you can just do a copy, paste into your CSS file, and make modifications from there.
The only section I did not do this for was the calendar, because I have previously posted all the calendar styles in a clean, condensed CSS file for your use.
Enjoy! As with anything, there may be a mistake or two. If you do a copy and it is not the correct style, please let me know.
