| Tag/Attribute | Value |
| <img> | Below are the image map-specific attributes to use with <img>. Regular <img> attributes apply. |
| usemap | The name of the map with a hash symbol prepended to it. For example, for a map with name=“map”, the image should have usemap=“#map”. |
| <map> | |
| name | The name of the map to identify it. To be used with the image’s usemap attribute. |
| <area> | Below are <area>-specific attributes. When href is specified, making the <area> a link, <area> also supports all of the attributes of the anchor tag (<a>) except ping. See them at the MDN docs. |
| alt | The alternate text to display if images are not supported. This is only necessary if href is also set on the <area>. |
| coords | The coordinates outlining the selectable area. When shape=“polygon”, this should be set to a list of “x, y” pairs separated by commas (i.e., shape=“polygon” coords=“x1, y1, x2, y2, x3, y3, …”). When shape=”rectangle”, this should be set to left, top, right, bottom. When shape=“circle”, this should be set to centerX, centerY, radius. |
| href | The URL of the hyperlink, if specified. If it is omitted, then the <area> will not represent a hyperlink. |
| shape | The shape of the <area>. Can be set to default to select the entire image (no coords attribute necessary), circle or circ for a circle, rectangle or rect for a rectangle, and polygon or poly for a polygonal area specified by corner points. |
Description
An image maps is an image with clickable areas that usually act as hyperlinks.
The image is defined by the <img> tag, and the map is defined by a <map> tag with <area> tags to denote each clickable area. Use the usemap and name attributes to bind the image and the map.
Basic Example
To create an image map so that each of the shapes in the image below are clickable:
The code would be as follows:
<img src="http://jaced.com/blogpix/2007/trisquarecircle/002.gif" usemap="#shapes"> <map name="shapes"> <area shape="polygon" coords="79,6,5,134,153,134"> <area shape="rectangle" coords="177,6,306,134"> <area shape="circle" coords="397,71,65"> </map>
You should see that the browser recognizes the areas when the cursor becomes a pointer. See a live demo on
