🙋 Introduction

The <map> tag in HTML is a powerful element used for creating image maps, allowing developers to define clickable areas within an image.

This guide will provide a comprehensive overview of the HTML <map> tag and how to effectively implement image mapping.

🤔 What is <map> Tag?

The <map> tag is employed in conjunction with the <area> tag to define clickable regions within an image. This feature is particularly useful for creating interactive graphics, diagrams, or navigation menus on web pages.

💡 Syntax

To use the <map> tag, you need to associate it with an image using the usemap attribute in the <img> tag. Additionally, define clickable areas within the image using the <area> tag.

<map name="map-name">
  <area shape="rect" coords="x1,y1,x2,y2" href="link1.html" alt="Area 1">
  <area shape="circle" coords="x,y,r" href="link2.html" alt="Area 2">
  <area shape="poly" coords="x1,y1,x2,y2,x3,y3" href="link3.html" alt="Area 3">
</map>

🧰 Attributes

name (in <map>): Assigns a name to the map, allowing the <img> tag to reference it through the usemap attribute.
shape (in <area>): Specifies the shape of the clickable area. Common values include rect (rectangle), circle (circle), and poly (polygon).
coords (in <area>): Defines the coordinates of the clickable area. The values depend on the shape (e.g., for rect, it's x1,y1,x2,y2).
href (in <area>): Specifies the URL to navigate to when the clickable area is activated.

📚 Common Use Cases
