[Commentor] LC-344 Elliotte Harold [Comment] Section 5.3.7 states: [BACKGROUND_IMAGE_SUPPORT] Do not use background images unless you know the device supports them. (Normative) I don't see any reasoning in the document to justify this one, and I can't think of any myself. Won;t a device that doesn't support background images simply ignore them without any detrimental effects? I can;t think of any examples in practice where the background image was a critical part of the content. This feels like it would degrade gracefully. At a minimum, I would ask that this normative rule be explained more. But if there's no good explanation for this, then this rule could simply be dropped. [Working Group decision] The group agreed this Best Practice wasn't very relevant and decided to remove it. [Commentor reply]
