Syntax

<tfoot> content </tfoot>

Discussion

The tfoot element defines a footer for a table. This element is only a structural definition and by default does not render anything unique, so the HTML specified by content should contain the other structural elements such as table rows (tr) and table cells (td).

The meter element was introduced in the HTML5 specification.

th

Defines header text for a table column.

Syntax

<th> content </th>

Discussion

Table headers should be placed in their own table row, usually the first row in a table definition, and should correspond in number to table cell definitions in later rows. In Safari, the text specified by content is displayed in a bold face.

thead

Defines a table’s header.

Syntax

<thead> content </thead>

Discussion

The thead element defines a header for a table. This element is only a structural definition and by default does not render anything unique, so the HTML specified by content should contain the other structural elements such as table rows (tr) and table cells (td).

title

Defines the visible window title for the page.

Syntax

<title> content </title>

Discussion

The text specified by content is displayed at the top of a browser window, but remains invisible in embedded WebKit web views unless requested programatically. The title element must be placed in the head section of a page.

tr

Defines a table row.

Syntax

<tr> content </tr>

Discussion

The tr element defines a row within a table. Table cells are usually enclosed by these rows. Consecutive table rows are placed vertically onscreen.

track

Specifies a text component of the parent audio or video element.

Syntax

<video src="mysource.mp4">

<track kind="captions" src="myCaptions.srt">

<track kind="description" src="myDescription.srt">

</video>

Discussion

The track element can indicate subtitles, captions, description, chapters or metadata through the kind attribute. See Safari HTML5 Audio and Video Guide for more information.

Availability

The track element was introduced in the HTML5 specification.

tt

Obsolete. Displays text in a "teletype" style. Use CSS styling instead.

Discussion

The text is displayed in a monospaced "teletype" style, but otherwise matches the style of the enclosing element. Styles should be more finely tuned using CSS instead of using HTML style elements. Semantic HTML alternatives to tt include: kdb for keyboard input, var for variables, code for computer code, and samp for computer output.

Availability

The tt element has been declared obsolete in the HTML5 specification.

u

Deprecated. Defines a block of underlined text. Use CSS styling instead.

Discussion

The content is underlined. The ins element is more appropriate for this function. Styles should be more finely tuned using CSS instead of using HTML style elements. Additionally, underlined text should not be used as it might be confused with actual hyperlinks.

Availability

The u element has been deprecated in the HTML 4.01 standard.

ul

Specifies an unordered list.

Syntax

<ul> content </ul>

Discussion

The ul element specifies an unordered, bulleted list. Within the bounds of this block, list items should be defined using the li element.

var

Specifies a variable.

Syntax

<var> content </var>

Discussion

The var element specifies a variable. The text enclosed within the element is italicized.

video

Embeds video into a webpage.

Syntax

<video src="url"

poster="freezeframe.png"

autoplay="autoplay" <!-- Boolean attribute. Omit to prevent autoplay. -->

start="00:00:00.00"

loopstart="00:00:00.07" <!-- 7 seconds -->

loopend="00:00:00.19"

end="00:00:00.27"

playcount="4" <!-- play 4x -->

controls="true"

width="640"

height="480"

>

Discussion

The video element might contain fallback content for browsers that do not support this element. Any content enclosed within the video element is ignored by browsers that support the video element (but it must be valid HTML).

The video element supports inclusion of source elements to provide multiple versions of a video clip encoded with different codecs, at different bit rates, and so on. These source elements must be the first elements inside the video element before any fallback content. See source for more information.

wbr

Specifies a block in which line breaks are permitted.

Syntax

<wbr> content </wbr>

Discussion

Within a nobr block (in which line breaks are enabled), any content specified by content is permitted to use line breaks. The line breaks themselves must still be requested using the br element.

xmp

Obsolete. Represents a block of literal text. Use pre and code instead.

Discussion

The xmp element preserves the formatting of the block of text, specifically line breaks, multiple spaces, and the greater-than and less-than symbols that accompany HTML elements. This block is also prefaced with a newline element. In Safari, text enclosed in this element is also rendered in a monospace "teletype" font.

Availability

The xmp element has been declared obsolete in the HTML5 specification.
