HTML alt Attribute ❮ Prev Next ❯

The HTML alt attribute is used in HTML and XHTML documents. It specifies an alternative text which must be rendered if the element cannot be displayed for some reason. The alt attribute can also be used by screen readers to allow visually impaired users to interact with a webpage. To be accessible, an image must have an alt attribute. However, it may not contain text (empty or null attribute).

You can use the alt attribute on the following elements: <area>, <img>, <input>.

It is required to use the alt attribute for the <img> element. For <input> elements, you can only use the alt attribute with <input type="image">.

Syntax

<img alt="alternative text"> <area alt="alternative text">

Use the title attribute to create a tooltip for an image.

Example of the HTML alt attribute used on the <area> element:

<!DOCTYPE html> <html> <head> <title>Title of the document</title> </head> <body> <p>Click on the logo or on one of the logo item to watch it closer:</p> <img src="/uploads/media/news_gallery/0001/01/thumb_316_news_gallery_list.jpeg" width="250" height="150" alt="block" usemap="#blockmap"> <map name="blockmap"> <area shape="circle" coords="50,32,25" alt="html" href="/uploads/media/book_gallery/0001/01/d450f0358f947dffb3af91195c3002600d74101b.png"> <area shape="circle" coords="218,115,25" alt="css" href="/uploads/media/book_gallery/0001/01/25521e981b34da57c8f51baddc5b76351b855818.png"> <area shape="circle" coords="195,32,28" alt="php" href="/uploads/media/book_gallery/0001/01/4bbee6698c4884f25c46010d61b658dd62d2c04f.png"> <area class="homepage" shape="rect" coords="90,90,35,55" alt="php" href="https://www.w3docs.com/"> </map> </body> </html> Try it Yourself »
