Map Tag in HTML5

Introduction

An image-map is an image with clickable areas. The <map> tag is supported in all major browsers. An image map is one image with multiple "clickable" areas. Attributes consist of a name and a value separated by an equals (=) sign, with the value surrounded by double-quotes. This attribute is associated with the <img>'s usemap attribute and creates a relationship between the image and the map.

Image

First of all, you need a suitable graphic. An image that cannot be divided into different sections is not your best choice, but an image that has clear cut-offs or lines would be better. Of course, this does not apply to navigational menus or similar, just to everyday pictures like animals, objects or people.

Co-ordinates

You'll need different co-ordinates depending on what sort of "hot spot" you'd like to use.

Hot Spot

Now that you've got your image and co-ordinates. There are three different shapes (commonly termed "hot spots") that can be used in image maps. They are as follows:
-RECT
-CIRCLE

-POLYGON

Attributes

HTML tags can contain one or more attributes. Attributes are added to a tag to provide the browser with more information about how the tag should appear or behave.

Attributes consist of a name and a value separated by an equals (=) sign, with the value surrounded by double-quotes.

There are 3 kinds of attributes that you can add to your HTML tags: Element-specific, global, and event handler content attributes.

Element-Specific Attributes

The following table shows the attributes that are specific to this tag/element.

<area> Tag

The HTML <area> tag is used for defining an area in an image map. Image maps are images with clickable areas (sometimes referred to as "hotspots") that usually link to another page.

alt - Alternate text. This specifies text to be used in case the browser/user agent can't render the image.

coords - Specifies the coordinates of the clickable area. Coordinates are specified as follows:

rect: left, top, right, bottom
circle: center-x, center-y, radius
poly: x1, y1, x2, y2, ...

shape - Defines a shape for the clickable area. Possible values:default

rect
circle
poly

href - Specifies the URL of a page or the name of the anchor that the link goes to.
target - Specifies the target frame to load the page into.

For example

<!DOCTYPE html>
<html>
<head>
<title>Image Map</title>
</head>
<body>
<img src ="image1.gif"
width="225" height="151" border="0"
alt="Mueller Hut, Mount Cook, and I"
usemap ="#muellermap" />
<map id ="muellermap"
name="muellermap">
<area shape ="rect" coords ="90,80,120,151"
href ="http://c-sharpcorner.com;"
alt="Me" />
<area shape ="poly" coords ="55,55,120,80,90,80,90,100,70,100,20,80,55,55"
