Quick answers

Frequently asked questions.

What is alt text?

A short description of an image in its alt attribute. Screen readers read it aloud, and search engines use it to understand what the image shows.

Is an empty alt ever right?

Yes, for purely decorative images such as dividers. alt="" tells screen readers to skip them. Images that carry meaning need real text.

How long should alt text be?

Usually one short sentence. Describe what is in the picture; there is no need to start with "image of".
