Alt Text Functions

When should you not use alt text?
Including alt text for decorative images or items
Decorative items such as dividers or design items that don't provide additional context or content don't need alt text. They don't add to the information a user needs and they make little sense, or are unnecessary, when read with a screen reader.

Definition and Usage
The alt attribute specifies an alternate text for an area, if the image cannot be displayed. The alt attribute provides alternative information for an image if a user for some reason cannot view it (because of slow connection, an error in the src attribute, or if the user uses a screen reader).
