B.2. HTML Quick Reference

As with the other sections of this book, we use the Netscape and Internet Explorer icons to the far right of each item to indicate tags and attributes that are extensions to the HTML 4.01 and XHTML 1.0 standards. If no icon is shown, the tag or attribute is part of the HTML 4.01 and XHTML 1.0 standards.

We include each tag's possible attributes (some required) indented below their respective tags. In the description, we give possible attribute values as either a range of integer numbers or a definitive list of options, where possible.
