Section B.2. HTML Quick Reference


B.2. HTML Quick Reference

We use the alert icon 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. We use the Internet Explorer icon to identify those extension tags and attributes that are unique to Internet Explorer and are not well supported by the other popular browsers. Even though we include them in the main text, we have not included here any of the antiquated or obsolete elements or attributes that are explicitly not part of the standards and are no longer supported by any browser.

We include the 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.
