ARIA labels, or Accessible Rich Internet Application labels, are a type of code attribute that allows developers to add descriptions and context to the elements on a webpage for users of screen readers.
ARIA labels can be used as labels for text fields, interactive widgets like accordion or slider controls, or as supplementary text for links and buttons.
If you have a number of similar links on a page, such as ‘learn more’ or ‘get started’ you would use an ARIA label to better identify the topic of these links, such as writing “Get started with accessibility today”.
