HTML ismap Attribute

Definition and Usage

The ismap attribute is a boolean attribute.

When present, it specifies that the image is part of a server-side image map (an image map is an image with clickable areas).

When clicking on a server-side image map, the click coordinates are sent to the server as a URL query string.

With the help of these click coordinates, the server returns the desired output.

Note: The ismap attribute is allowed only if the <img> element is a descendant of an <a> element with a valid href attribute.
