You may also find the resources for my HTML books useful when personalizing your blog. I've got several different color tables, a full (X)HTML reference guide (Appendix A), a full CSS Reference (Appendix B), a list of common
DOCTYPE declarations, a complete set of the entity references that can be used in HTML and XHTML for inserting special characters and symbols, and CGI scripts.
There's also an Extra Tips section. Check it out!
