Appendix B. List of Attributes

Most HTML tags rely on attributes to modify their behavior and make them more useful. With so many available tags and attributes, it’s easy to forget which tag goes with which attributes. For instance, you may know that you want to set the padding value for a table, but you can’t remember which tag takes the cellpadding attribute (the answer to this one is <table>).

The following table provides an alphabetical list of all attributes as listed in the HTML 4.01 specification. The “Related Elements” column provides a list of tags that can use that attribute. The table also lists:

• Accepted values for each tag

• Whether the attribute is required

• A description of the attribute’s use

• Whether the attribute has been deprecated (indicated by a D in the “Depr.” column)

Note that some attributes appear more than once in the list. This is due to the fact that they may be used differently or may take different values depending on the tag in which they are used.

Name	Related elements	Values	Depr.	Comment
abbr	TD, TH	text		Abbreviated name for table cell
accept-charset	FORM	list		List of supported character sets
accept	INPUT, FORM	MIME types		List of MIME types for file upload
accesskey	A, AREA, BUTTON, INPUT, LABEL, LEGEND, TEXTAREA	single character		Assigns a shortcut key that brings focus to (activates) the element
action (required)	FORM	URL		Location of the CGI form processor on the server
