Answer Posted / chaitu

The longdesc attribute of the img element has been around since HTML 4 and is also valid in HTML5. This attribute is designed to provide a more detailed description of an image, compared to the information offered in the alt attribute. The interesting thing is that instead of providing a description by itself (like the alt attribute does), longdesc points to a hyperlink containing the description.

An example of the use of longdesc is presented below:

<img src="italy.jpg"

alt="This image represents the map of Italy" longdesc="italy.html#description">

<!-- other content here ... -->

<section id="description">

<h2>Italy</h2>

<p>The shown map of Italy illustrates its division

in regions...</p>

</section>
