HTML Image Maps: With HTML image maps, you can create clickable areas on an image.

Using HTML map tags, you can create a clickable map.

By tapping the HTML map region, the user will open links provided.

The clickable places are defined using <area> elements.

You can’t avoid the ending tag while creating an HTML image map.


Image Maps

The HTML <tag> tag defines an image map. An image map is an image with clickable areas. The areas are defined with one or more <area> tags.

Here is the HTML source code for the image map above:

<img src="workplace.jpg" alt="Workplace" usemap="#workmap">

<map name="workmap">
  <area shape="rect" coords="34,44,270,350" alt="Computer" href="computer.htm">
  <area shape="rect" coords="290,172,333,250" alt="Phone" href="phone.htm">
  <area shape="circle" coords="337,300,44" alt="Coffee" href="coffee.htm">

How Does it Work?

The thought behind a picture map is that you ought to have the option to perform various activities relying upon where in the picture you click.

To create an image map you need a picture, and some HTML code that depicts the clickable areas.

The Image

The image is inserted using the <img> tag. The only difference from different pictures is that you should add a usemap attribute:

<img src="workplace.jpg" alt="Workplace" usemap="#workmap">

The usemap value begins with a hash tag # followed by the name of the picture map, and is used to create a relationship between the image and the image map.

Tip: You can use any image as an image map!

Create Image Map

At that point, add a <map> element.

The <map> element is used to create an image map, and is linked to the picture by using the necessary name attribute:

<map name="workmap">

The name attribute should have a similar value as the <img>’s usemap attribute.

The Areas

At that point, add the clickable areas.

A clickable area is defined using an <area> element.


You should define the shape of the clickable area, and you can pick one of these values:

• rect – defines a rectangular region

• circle – defines a circular region

• poly – defines a polygonal region

• default – defines the whole region

You should likewise define a few directions to have the option to put the clickable region onto the picture.


The coordinates for shape=”rect” come in pairs, one for the x-axis and one for the y-axis.

In this way, the directions 34,44 is found 34 pixels from the left edge and 44 pixels from the top:

The directions 270,350 is found 270 pixels from the left edge and 350 pixels from the top:

Presently we have sufficient data to create a clickable rectangular region:


<area shape="rect" coords="34, 44, 270, 350" href="computer.htm">

This is the area that becomes clickable and will send the user to the page “computer.htm”:


To add a circle region, first find the directions of the focal point of the circle:


At that point indicate the range of the circle:

44 pixels

Presently you have sufficient data to create a clickable circular region:


<area shape="circle" coords="337, 300, 44" href="coffee.htm">

This is the region that gets clickable and will send the user to the page “coffee.htm”:


The shape=”poly” contains a few organize focuses, which creates a shape formed with straight lines (a polygon).

This can be used to create any shape.

Like perhaps a croissant shape!

How might we make the croissant in the picture beneath become a clickable link?

We need to track down the x and y coordinates for all edges of the croissant:

The directions come two by two, one for the x-axis and one for the y-axis:


<area shape="poly" coords="140,121,181,116,204,160,204,222,191,270,140,329,85,355,58,352,37,322,40,259,103,161,128,147" href="croissant.htm">

This is the region that gets clickable and will send the user to the page “croissant.htm”:

Image Map and JavaScript

A clickable region can likewise trigger a JavaScript function.

Add a click occasion to the <area> element to execute a JavaScript function:

Here, we use the onclick attribute to execute a JavaScript function when the area is clicked:

<map name="workmap">
  <area shape="circle" coords="337,300,44" href="coffee.htm" onclick="myFunction()">

function myFunction() {
  alert("You clicked the coffee cup!");

Chapter Summary

• Use the HTML <map> element to define an image map

• Use the HTML <area> element to define the clickable regions in the picture map

• Use the HTML usemap attribute of the <img> element to highlight a picture map
