HTML and CSS Reference
In-Depth Information
N OTE HTML5 defines a number of rel values for <area> . See the earlier “<a> (Anchor)” section
for a list of the values used with the rel attribute.
shape This attribute defines the shape of the associated hot spot. HTML 4 defines the
values rect , which defines a rectangular region; circle , which defines a circular region;
poly , which defines a polygon; and default , which indicates the entire region beyond any
defined shapes. Many browsers, notably Internet Explorer 4 and higher, support alternate
values for shapes, including circ , polygon , and rectangle .
target This attribute specifies the target window for hyperlink-referencing frames. The
value is a frame name or one of several special names. A value of _blank indicates a new
window. A value of _parent indicates the parent frame set containing the source link.
A value of _self indicates the frame containing the source link. A value of _top indicates
the full browser window.
type This attribute specifies the media type in the form of a MIME type for the link target.
Generally, this is provided strictly as advisory information; however, in the future a browser
might add a small icon for multimedia types. For example, a browser might add a small
speaker icon when type is set to audio/wav . For a complete list of recognized MIME types,
see The attribute is commonly
understood for the a element but was introduced by HTML5 to image maps.
