QUESTIONAIRE ISSUES

 

 

1.1.  L1  SUCCESS CRITERIA 4

 

 

Using null
<http://www.w3.org/TR/2005/WD-WCAG20-HTML-TECHS-20050630/Overview.html#image
s-as-spacers>  alt text
(http://www.w3.org/TR/2005/WD-WCAG20-HTML-TECHS-20050630/Overview.html#image
s-as-spacers) and no title attribute on img elements for images that are
purely decorative.

 

Some people find that all non-text elements should have a text alternative
(issue 1703),


 so the second bullet may be debatable. 


I don't see why spacer images should have a text alternative


 (except an empty string).

----------------------

 

 

What if no technique for causing decorative items to be ignored 

 

Then does   4.2  L1 SC1   kick in???   pretty dramatic for a spacer image. 

 

When would this occur  - where you had images for example but no alt form.

 

hmmmmm
