Comments Re: CynthiaSays and Your Question:


The page being discussed is: http://www.cookiecrook.com/weblog.php


For the question......

Cynthia Says looks for anchor elements that contain an HREF attribute in
them, and then makes sure that there is another character between it and the
next link where the next link also contains an href attribute.
Cynthia Says does not detect a failure on this page for this checkpoint
because you do not have two adjacent anchor tags with href attributes not
separated by a character.  Bobby is detecting the anchor with an "href" next
to an anchor with an "id" attribute as a failure, and it is not a failure,
because the anchor with the "id" attribute only is not a link.

The WCAG checkpoint [1] this is referring to is:
10.5 Until user agents (including assistive technologies) render adjacent
links distinctly, include non-link, printable characters (surrounded by
spaces) between adjacent links. [Priority 3]

The technique that the WCAG guidelines provide to assist in addressing this
issue [2] refers to grouped links, such as navigation bars.


For the question......

The technique that the WCAG guidelines provide to assist in addressing this
issue [3] refers to using the title attribute in addition to "clear" link
text.  Cynthia Says does not flag these links as errors because of the
distinct title attribute value, however, it does present a warning for each
of these links because the link text, itself, is identical and should be
looked at to see if it could be made clearer.
The warning does not cause the Cynthia Says report to fail.
