What is alternative text?

Alternative text or alt text is a word or phrase which gives context to an image to users of assistive technology. Alt text provides a description and function of an image for:

• Les utilisateurs aveugles ou ceux dont la vision est affectée
• users with cognitive disabilities
• Les utilisateurs qui ont désactivé les images pour consommer moins de données.

In addition, if the URL of an image link is broken or changed the alt text appears in its place. This can improve the user experience for those experiencing technical issues on a webpage. Below is the alt text of the image logo on the Silvertone Hills good site homepage.
