🙋 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.
<img src="your-image.jpg" alt="Your Image" usemap="#map-name">
<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
