Image mapping is a technique that allows different parts of an image to be clickable, linking to different web pages or performing other actions. This is achieved by defining specific areas within the image, known as hotspots, and assigning them a specific URL or action.
How Does Image Mapping Work?
Image mapping works by defining specific areas within an image using the tag and assigning them a specific URL or action using the tag. The tag defines the image as a clickable map, while the tag defines the specific hotspots within the image.
Example:
Here is an example of an image map:
In this example, the image has three hotspots defined using the tag. The first hotspot is a rectangle with coordinates (0,0,100,100) that links to page1.html. The second hotspot is a circle with coordinates (150,150,50) that links to page2.html. The third hotspot is a polygon with coordinates (225,225,300,300,225,375,150,300) that links to page3.html.
