[Accessibility_sig] Alt tags

[Jan Heck]

Hi, Mary,
 
I think it's best if you don't include a space between the two quotation
marks, i.e., alt="" rather than alt=" ".  I don't know if that will help it
validate with HTML Tidy, but I have used other validators that have no
problem with the null alt text, and it passes accessibility checks as well.

Subject: [Accessibility_sig] Alt tags


Hi there,
 
We have a question about alt tags. We've heard that alt tags for things like
transparent gifs are an annoyance for people using screen readers, who don't
want to read "transparent gif" over and over again. When we try to use alt="
" as an alternative, our code does not validate as compliant with HTML 4.01
standards (using HTML Tidy).
 
Does anyone know of a way to be compliant *and* convenient? Or, has anyone
had experience validating their HTML that shows that alt=" " is actual
compliant?
