aria-label on links:
- Jaws V.11 and greater has complete support.
- ChromeVox V.1 and greater has complete support
- VoiceOver V.3 and greater ??
The objective of this technique is to describe the purpose of a link using the
aria-label attribute. The
aria-label attribute provides a way to place a descriptive text label on an object, such as a link, when there are no elements visible on the page that describe the object. If descriptive elements are visible on the page, the
aria-labelledby attribute should be used instead of
aria-label. Providing a descriptive text label lets a user distinguish the link from links in the Web page that lead to other destinations and helps the user determine whether to follow the link.
The WAI-ARIA specification text alternative computation algorithm states that the aria-label text will override the text supplied within the link. As such the text supplied will be used instead of the link text by AT. Due to this it is best practice to start the text used in aria-label with the text used within the link. This will allow consistent communication between users.
Describing the purpose of a link in HTML using the aria-label element. The words 'read more' are repeated in the aria-label because the original anchor text 'read more' will be replaced by the aria-label.
