Rule LINK-2
Link text should be meaningful when taken out of context; therefore, links that point to different URIs should be unique.

Description

Best Practice Type: Pass/Warning

Link text should be meaningful when taken out of context; therefore, links that point to different URIs should be unique.

Notes

  • The text content of a link can be hidden to make the link that might otherwise appear confusing to screen reader users unique and meaningful by using the following techniques:
    1. Include span or other element within the link to hide additional text content.
    2. Define alt attribute content for an img or area element.
  • The effective link text of links that contain images will include the alt attribute content, in the order of appearance in the document of the images, in addition to the text content of the link.
  • Automated validators will remove common default file names from a URI for the purpose of comparison, but maintain any additional URI information that follows the default file name. Examples of default file names are:
    1. index.& (i.e. index.html, index.htm, index.php, etc)
    2. default.& (i.e. default.html, default.htm, default.asp, etc)
