http://dev.w3.org/html5/spec/Overview.html#the-canvas (why is the background blue rather than green?) Kudos for good advice here: Authors should not use the canvas element in a document when a more suitable element is available. When authors use the canvas element, they should also provide content that, when presented to the user, conveys essentially the same function or purpose as the bitmap canvas. - Indeed. And when we sort out HOW we recommend people do this (see other threads on alternatives/equivalents) we should update this section with that practical advice. The canvas must initially be fully transparent black. 1. "transparent black" ? Transparent I understand. Why black? This would be adjustable through CSS? (If so, why not make it "transparent" like all other elements?) 2. can we move this paragraph a bit further along so that all paragraphs relating to width and height are grouped together? It does seem like SVG could provide similar functionality BUT I don't know either (canvas nor SVG) well enough to make informed comments. I'm not sure either help me with the main use case I struggle with today, namely accessible diagrams and charts (which I normally wind up addressing with structured data - lists and/or tables - and images, occasionally image maps). So it seems OK, but I'd take this review with a grain of salt as I'm not that familiar with canvas and not sure yet what I'll use it for. The introduction bits read ok (the implementation I skimmed).
