HTML <area> tag

Function:

The HTML <a> tag is used for defining an area in an image map.

Difference between HTML and XHTML:

In HTML the <area> tag has no end tag.

In XHTML the <area> tag must be properly closed.

Example:

<img src=/images/usemap.gif alt="usemap" border="0" 
     usemap="#tutorials"/>
<map name="tutorials">
   <area shape="poly" 
            coords="74,0,113,29,98,72,52,72,38,27"
            href="/perl/index.htm" 
            alt="Perl Tutorial"
            target="_blank" />
   <area shape="rect" 
            coords="22,83,126,125"
            alt="HTML Tutorial"
            href="/html/index.htm" 
            target="_blank" />
   <area shape="circle" 
            coords="73,168,32"
            alt="PHP Tutorial"
	    href="/php/index.htm" 
            target="_blank" />
</map>
