Hey there,

alt stands for "alternative" and is used for two main reasons.

  1. Many people have auto-loading for images disabled in their browsers, so when the image doesn't load (or can't load) the "alternative text" you provide is what will be displayed instead of the image. So, the users may not see the image, but they will see what the image is about.

  2. For screen readers used by the visually impaired. A screen reader will use the "alternative text" to provide an audio description of the image.

So, both those are the reason you use the alt, and both those show why it is very important to provide a short but specific description in the alt attribute.

Hope that clears it up for you. :dizzy:
