Rijk's panelizer

The "Add panel" button adds an entry to Opera 12's or Firefox's bookmarks or Mozilla/Seamonkey's panels list. The page will be directly available as a panel in Opera's "Panels" (F4) or Mozilla's/Seamonkey's "Sidebar" (F9). In the case of Firefox, open the page in the "Sidebar" by selecting it from the Bookmarks.

Opera 15 will not support panels, and neither do Chrome, Safari or IE, so for those browsers you are better off with my standalone Quick Reference pages for HTML, CSS and HTTP/1.1.
