See Understanding Techniques for WCAG Success Criteria for important information about the usage of these informative techniques and how they relate to the normative WCAG 2.0 success criteria. The Applicability section explains the scope of the technique, and the presence of techniques for a specific technology does not imply that the technology can be used in all situations to create content that meets WCAG 2.0.
HTML and XHTML
This technique relates to:
The objective of this technique is to demonstrate how to use a title
attribute on an anchor element to provide additional text describing a link. The
title
attribute is used to provide additional information to help clarify
or further describe the purpose of a link. If the supplementary information provided
through the title
attribute is something the user should know before
following the link, such as a warning, then it should be provided in the link text
rather than in the title
attribute.
Because of the extensive user agent limitations in supporting access to the title attribute, authors should use caution in applying this technique. For this reason, it is preferred that the author use technique C7: Using CSS to hide a portion of the link text (CSS) or H30: Providing link text that describes the purpose of a link for anchor elements.
Example Code:
<a href="http://example.com/WORLD/africa/kenya.elephants.ap/index.html"
title="Read more about failed elephant evacuation">
Evacuation Crumbles Under Jumbo load
</a>
In HTML 4.01 the
target="_blank"
attribute can be used on an anchor
element to indicate that the URI specified by the href
attribute will be opened in a
new window. This example shows using the title
attribute of the anchor
element to provide information that the link will be opened in a new window.
Example Code:
<a href="http://example.com/subscribe.html"
target="_blank"
title="link opens in new window">
Subscribe to email notifications about breaking news
</a>
Resources are for information purposes only, no endorsement implied.
Examine the source code for anchor elements.
For each anchor element that has a title
attribute, check that the
title
attribute together with the link text describes the purpose
of the link.
Check #1 is true.
If this is a sufficient technique for a success criterion, failing this test procedure does not necessarily mean that the success criterion has not been satisfied in some other way, only that this technique has not been successfully implemented and can not be used to claim conformance.
