Clarify link purpose requirements
LJWatson opened this issue · comments
In Understanding WCAG it says:
"Make sure the purpose of a link is obvious from either the link text or the surrounding content ("
When you drill into the requirements for this, it says that the purpose of the link must be understandable from its link text, or from its surrounding content *if that relationship can be understood by screen readers and the like. The reality is that most of the time ATs can't determine that relationship, so we should simplify this to:
"•Make sure the purpose of a link is obvious from the link text, or from additional content associated with the link"
The objective of this technique is to describe the purpose of a link by providing descriptive text as the content of the element. Please refer the WCAG Success criteria of link purpose.
