HTML area tag

id (name)

The "id" attribute assigns an identifier to the associated element. This identifier must be unique in the document and can be used to refer to that element.

Example:

class (cdata)

The "class" attribute assigns a class name (or a list of class names separated by spaces) to the container element. It's used with style sheets and tells the browser the class to which the element is associated with. A class gives visual attributes to elements.

Example:

style (style)

Defines a visual style of this element. Is a better practice to define styles attributes in external style sheets grouping them in classes. Attributes in the "style" parameter must preserve this order "name : value" and be separated by a semi-colon.

If you're writing XHTML code it's recommended not to use this attribute and try style sheet classes (with the "class" attribute).

Example:

title (text)

Indicates a title for the element. Used to give a short description about the element that is usually shown as a "tool tip" when the user put the mouse pointer over the element.

Example:

Code	View
<a title="HTMLQuick.com" href="http://www.htmlquick.com">HTML code</a>	HTML code

lang (langcode)

Specifies the language of an element's content. The default value in "unknown".

When writing XHTML code the syntax "xml:lang" represents a preferred alternative in XHTML 1.0 and a replacement in XHTML 1.1 (e.g., xml:lang="en").

Example:

dir

Specifies the text direction of the element's contents and attribute values, as well as tables directionality. It has two possible values that are case insensitive:

• RTL: Right to left.
• LTR: Left to right.

Example:

alt (text)

The "alt" attribute defines an alternate text designed to be a textual replacement for objects that are usually not supported by some browsers. It also serve as additional information for browsers that do support these objects (images, forms and applets). Browsers may display this text as a tool tip when the mouse is over the object.

This attribute is required when writing XHTML code.

Example:

Code	View
<img width="88" height="31" src="http://www.htmlquick.com/img/links/button.jpg" alt="HTMLQuick link button" />

href (uri)

Specifies the destination resource for the element. Commonly used to refer to pages in the same domain name or external pages.

Example:

Code	View
Link to page on this site: <a href="http://www.htmlquick.com/tutorials/links.html">Links in HTML tutorial</a><br /> Link to external site: <a href="http://www.w3.org">World Wide Web Consortium</a>	Link to page on this site: Links in HTML tutorial Link to external site: World Wide Web Consortium

target (frame-target)

Specifies the name of the frame where the destination document should be loaded. Refer to the frame-target type definition for further information.

tabindex (number)

Specifies the position of this element in the tabbing order. The tabbing order defines the sequence with all the elements than can receive the focus. Users can navigate this sequence via keyboard (usually with the "tab" key).

accesskey (character)

Stablish a relationship between this element and a character key, allowing the user to activate it with that key (usually when used together with the "alt" key). The activation result depends on the actual element's nature. For links, this action automatically follows the link, and other elements simply get the focus.

shape

Specifies the form of a shape used to define an area. Values are case-insensitive and may be one of these:

• default: Specifies the entire region.
• rect: Define a rectangular region.
• circle: Define a circular region.
• poly: Define a polygonal region.

coords

Defines the coordinates and position of a shape. It's used together with the "shape" attribute, and the coordinates depend of the "shape" value:

• rect: left-x, top-y, right-x, bottom-y.
• circle: center-x, center-y, radius. If the radius is measured in percentage, its calculated as that percentage of the smaller size of the associated object.
• poly: x1, y1, x2, y2, ..., xN, yN. This defines a closed polygon. If you define an open polygon, the browser should close it by adding a segment from the first point to the last one.

Coordinates are relative to the top-left corner of the associated object. Each coordinate is of length type and are separated by commas.

nohref

When set, this boolean attribute specifies that a region has no associated link. The value is case-insensitive.

Remember that boolean attributes must be defined as attr_name="attr_name" to be XHTML code compatible.
