If the image isn't providing the user any informative content or enhancing greater understanding of the content, then the alt attribute must be empty." 1) Remove the word empty and replace it with "must have a null value" 2) Two low vision members of the WCAG mentioned today that CSS background images mess with the contrast changes they try to make. So I suggest remove "or preferably use CSS techniques" http://lists.w3.org/Archives/Public/w3c-wai-gl/2014AprJun/0122.html http://lists.w3.org/Archives/Public/w3c-wai-gl/2014AprJun/0121.html 106809 2 david100 2014-05-26 21:49:04 +0000 I withdraw and save for next round 117580 3 shane 2015-01-29 17:29:41 +0000 Moved into LC1 component as per discussion in HTML A11Y Task Force on 29 January 2015 117592 4 shane 2015-01-29 18:49:55 +0000 The language in the section had changed some since the original comment. Proposed change is: <p>Purely decorative images are visual enhancements, decorations, or embellishments that provide no function or information beyond aesthetics to users who can view the images.</p> <p>Mark up purely decorative images so they can be ignored by assistive technology by using an empty <code>alt</code> attribute (alt=""). </p> <p class='note'>An alternate technique is to include the image using CSS. This is NOT recommended, as CSS background images can make it difficult for visually impaired users to enable "high contrast" mode.</p> 126279 5 lwatson 2016-04-28 16:26:47 +0000 Moved to HTML on Github https://github.com/w3c/html/issues/307
