The  element is used to apply a style to text which doesn't play any structural role, or where use of standard HTML elements is not desirable. For example, it may be useful for text to be highlighted by rendering it with a different background colour. For text such as this, using a standard HTML element such as  with an applied style, would possibly be inappropriate, because browsers that don’t support style sheets would render the text as italicised. The  element is recommended in such situations as other browsers simply ignore it.

The  element can be used within text blocks to apply a style as defined in a style sheet, according to a CLASS or ID attribute, or the STYLE can be specified within the  attribute. As with other elements used within the <BODY> of a HTML document,  can also have a certain style applied to it in the style sheet definition.

Internet Explorer also supports the use of the DIR attribute for specifying the reading direction of the text. Using :

causes the text to be rendered, reading from right to left, instead of the standard left to right. Note that this only occurs on systems that support right to left text rendering, for example, Arabic and Hebrew systems.

Viewing the source of any page of this reference may also provide some clues. The  element is used quite extensively for setting the styles of various text.

TITLE="informational ToolTip"
The Internet Explorer 4.0 (and above) specific TITLE attribute is used for informational purposes. If present, the value of the TITLE attribute is presented as a ToolTip when the users mouse hovers over the  section.

LANG="language setting"
The LANG attribute can be used to specify what language the  element is using. It accepts any valid ISO standard language abbreviation (for example "en" for English, "de" for German etc.) For more details, see the Document Localisation section for more details.

LANGUAGE="Scripting language"
The LANGUAGE attribute can be used to expressly specify which scripting language Internet Explorer 4.0 uses to interpret any scripting information used in the  element. It can accept values of vbscript, vbs, javascript or jscript. The first two specify the scripting language as Visual Basic Script, the latter two specify it as using Javascript (the default scripting language used if no LANGUAGE attribute is set.

CLASS="Style Sheet class name"
The CLASS attribute is used to specify the  element as using a particular style sheet class. See the Style Sheets topic for details.

STYLE="In line style setting"
As well as using previously defined style sheet settings, the  element can have in-line stylings attached to it. See the Style Sheets topic for details.

ID="Unique element identifier"
The ID attribute can be used to either reference a unique style sheet identifier, or to provide a unique name for the  element for scripting purposes. Any  element with an ID attribute can be directly manipulated in script by referencing its ID attribute, rather than working through the All collection to determine the element. See the Scripting introduction topic for more information.

DATAFLD
The DATAFLD attribute can be used to specify a data column name from the Data source (see DATASRC) that the  is bound to. For more information on the DATAFLD attribute, see the Data Binding topic.

DATAFORMATAS
When the  element is data-bound, it can accept straight text, or HTML from the data source. The DATAFORMATAS attribute should be set to "TEXT" or "HTML" accordingly. with DATAFORMATAS="HTML", the data provided for the  element is parsed and rendered when its displayed.
For more information on the DATAFORMATAS attribute, see the Data Binding topic.

DATASRC
The DATASRC attribute can be used to specify a data source that the  is bound to. For more information on the DATASRC attribute, see the Data Binding topic.

Every  element in a document is an object that can be manipulated through scripting. Note that scripting of the  element/object is only supported by Internet Explorer 4.0 in its Dynamic HTML object model. Netscape does not support direct scripting of the  element at all.

<SPAN...> Properties
The <SPAN...> element/object supports all of the standard Dynamic HTML properties (i.e. className, document, id, innerHTML, innerText, isTextEdit, lang, language, offsetHeight, offsetLeft, offsetParent, offsetTop, offsetWidth, outerHTML, outerText, parentElement, parentTextEdit, sourceIndex, style, tagName and title). Details of these can be found in the standard Dynamic HTML properties topics.
The  element also supports the following properties:

clientHeight
The clientHeight property reflects the height (in pixels) of the contents of the  element.

clientWidth
The clientWidth property reflects the width (in pixels) of the contents of the  element.

scrollHeight
The scrollHeight property reflects the contents of the  elements total scrollable height (in pixels).

scrollLeft
The scrollLeft property reflects a value representing the distance between the left-most edge of the element and the left-most visible edge of the element. While the contents of the  element are totally visible on the screen, the scrollLeft property is 0, only increasing if the left-most edge of the  elements contents are scrolled off the left hand edge of the current viewing window.

scrollTop
The scrollTop property returns a value that represents the distance between the top-most edge of the element and the top-most edge of the current viewing window. When used with the  element, the scrollTop property is a value indicative of the extent to which the referenced element has been scrolled vertically. If the contents of the  element are visible, then the scrollTop property will be 0, only increasing as the contents of the element are scrolled off the top of the current viewing window.

scrollWidth
Like the scrollHeight property, the scrollWidth property reflects a value that represents the total scrollable width of the contents of the  element.

<SPAN...> Methods
The <SPAN...> element/object supports all of the standard Dynamic HTML methods (i.e. click, contains, getAttribute, insertAdjacentHTML, insertAdjacentText, removeAttribute, scrollIntoView and setAttribute). Details of these can be found in the standard Dynamic HTML Methods topics.

<SPAN...> Events
The <SPAN...> element/object supports all of the standard Dynamic HTML events (i.e. onclick, ondblclick, ondragstart, onfilterchange, onhelp, onkeydown, onkeypress, onkeyup, onmousedown, onmousemove, onmouseout, onmouseover, onmouseup and onselectstart). Details of these can be found in the standard Dynamic HTML events topics.
