This document describes tags included in the abandoned HTML 3.0 draft and not incorporated into later darfts of HTML. They may have been implemented by some browsers, but should be considered obsolete.Click here to skip over the explanatory material at the top of the page and jump straight to the tags.
and these icons:
Support: 2.0, 3.0, 3.2 1.1+ 1.0+
alert you to tags and attributes that are not supported by all browsers. The support page explains the table and the icons in detail.
Not all HTML tags are in this single file. The comprehensive list has been split into the following eight categories:
We have also provided several indexes to help you navigate through this reference. In addition to our main indexes (the compact index and the complete index), there are four other indexes that list the tags according to the standards and browsers that support them.

The abbreviation tag defines an abbreviation. It is typically displayed just like normal text, but is used by automatic indexers.
The acronym tag defines an acronym. It is typically displayed just like normal text, but is used by automatic indexers.
The author tag defines text that names the author of a document. It is typically displayed just like normal text, but is used by automatic indexers.
The banner element defines an image or block of text that does not scroll with the document and is displayed at the top of the screen as the user scrolls through the document. Details of the attributes are not yet available -- use a BANNER attribute in the LINK section of the HEAD.
The credit tag defines text that credits a figure or quote. It is valid only within FIG or BQ tags.
The deleted text tag marks text that has been deleted, for example in a group authoring situation or a legal document.
See the OBJECT and MAP tags for an alternate to this tag.
The figure element is an improvement over the inline image used in HTML 2.0 for a variety of reasons. The text used to describe the figure for non-graphical browsers can contain
markup tags, and a separate credit and caption will be displayed by both graphical and non-graphical browsers. It also makes imagemaps much easier to code and independent of the
server. At the moment it isn't clear whether the built-in image maps of
FIG or the client-side image maps of
IMG with a
USEMAP attribute will emerge as the long term alternative to server
side image maps. The attributes of
- "URL" identifies the image source, typically a GIF or JPEG file.
- "alignment" should be one of TOP, MIDDLE, or BOTTOM. This causes the top, middle, or bottom of the image to be aligned with the text on the line containing the IMG tag.
"alignment" should be one of LEFT, RIGHT, TOP, TEXTTOP, MIDDLE, ABSMIDDLE, BASELINE, BOTTOM, or ABSBOTTOM.
- This specifies the height of the image, according to the UNITS attribute.
- This specifies the width of the image, according to the UNITS attribute.
- Here units is one of pixels, meaning the width and height are measured in pixels, or en, meaning the width and height are measured in en spaces. These units are not used for the shape co-ordinates of any anchor tags in the figure.
- Stops text from flowing around the figure.
- Points to a script that handles clicks and drags.
The figure-content contains the following optional elements, in this order:
</CAPTION>Figure description text, including markup (headers, lists, etc.) to substitute for the image.
The SHAPE attribute is one of:
This implements a figure with a built-in imagemap, freeing the browser from asking the server how to respond to a click. If the user clicks within the area defined by the anchor's SHAPE attribute, the link is followed. (If the click is outside all the defined shapes, the link identified as default is followed.) The numerical values provided are interpreted as pixels if they are integers, or as fractions of the screen width if they are not integers, with the origin at the top left corner of the figure. There is an intelligent mechanism for dealing with a click in an area that is in more than one shape anchor. If the browser does not display graphics, the figure description text is displayed, and some of it is highlighted as link text.
The footnote tag defines a footnote, ideally displayed in a pop-up window. The text that refers to this footnote does so with a standard anchor tag using anchor-name.
The horizontal tab tag is used to set or jump to a horizontal tab. The INDENT attribute specifies the amount in en spaces to set this indent to. The align attribute can be one of LEFT, RIGHT, CENTER, or DECIMAL and will position the following text to the tab accordingly. The dp sets the tab to the position that the next character is found The default character is ".".
The inserted text tag marks text that has been inserted, for example in a group authoring situation or a legal document.
The language tag is used to alter the language used for a block of text.
The list heading tag defines the heading for an ordered, unordered, or definition list. Other tags may be embedded in a list heading. It must come before any List Item (LI) or Definition Term (DT) tags in the list.
The math tag introduces a description of an equation or formula. math-content is not yet fully defined.
The note tag defines text that forms a note. Many browsers display it in an indented block surrounded by blank lines with a graphic. The CLASS attribute specifies the type of note, such as a warning, caution, or note. The graphic used will be based on the CLASS. The SRC attribute can be used to override the graphic that would be used by default.
Valid only within a figure (FIG), the overlay element speeds up image rendering by drawing small changes over a base figure. The attributes are:
- Here "URL" identifies the image source, typically a GIF or JPEG file.
- This specifies the offset to the right within the base image from the top left corner, according to the
- This specifies the offset to the bottom within the base image from the top left corner, according to the
- This specifies the height of the image, according to the
- This specifies the width of the image, according to the
- Here units is one of pixels, meaning the width and height are measured in pixels, or en, meaning the width and height are measured in en spaces.
- Points to a script that handles clicks and drags.
The person tag is used around names of people mentioned in a document. It is typically displayed just like normal text, but is used by automatic indexers
The quote tag defines text that should be displayed as a short quote. For English language documents this means the text will be surrounded with double quote (") symbols. Quotes nested within quotes will typically be displayed surround by single quote (') symbols.
<RANGE FROM="from id"
The range tag, which is valid only in the HEAD section, defines a range within the document. The FROM and UNTIL attributes refer to ID's of tags within the document. The SPOT tag can be used to specify a location in the document where there is no other tag.
The spot tag can be used to specify a location in the document where there is no tag.
