- What does
<map> HTML Tagdo?
- The <map> element is used in conjunction with one or more <area> elements to define hyperlinked regions of an image map.
Making Images Clickable
<map> element allows one or more images to be assigned to an image. It works by assigning coordinates to a rectangular area, and then assigning a link. Think of this like a series of hot spots, with coordinates defined in your code. As such,
<map> is commonly used to assign multiple navigation links to a single image at the top of the page. The image map is a client-side object, which means that the browser is responsible for interpreting the code and rendering the image map. This differs from server-side scripting, which is processed by the web server before the results are sent to the visitor’s browser.
<map>, you must first specify an image using the
<img src="/wp-content/uploads/shapes.png" width="487" height="271" alt="Shapes" usemap="#shapesmap">
The second step is creating the
<map> code, specifying the coordinates for the shapes you want to define within the
<area> element. Note that the
usemap attribute in the
<img> element matches the
name attribute of the
<map name="shapesmap"> <area shape="rect" coords="29,32,230,215" href="square.html" alt="Square"> <area shape="circle" coords="360,130,100" href="circle.html" alt="Circle"> </map>
The result looks like this. Move your mouse over the image to see the linked areas.
When a user clicks on the square in the image, they will be taken to the specified URL:
square.html. If they click on the circle, they will be taken to the
New in HTML 5
The HTML 5 specification introduces one important change to the attributes of the
<map> element. In HTML 5, if you choose to specify an
id attribute for your
<map>, you, must use exactly the same term for its
name attribute. Additionally, note that the accompanying
<img> must include a hashname, such as
#shapesmap, and not a URL.
