Hi all, May I suggest, with all due respect, that we return to the substance of this thread rather than debate questionable analogies and/or tangential issues? Is JS considered good WCAG 2.0 practice? First, Javascript is not a practice. It is a ubiquitous, useful, and enduring scripting language that is accessibility neutral. WCAG includes numerous sufficient techniques and failures that can inform implementations of javascript to improve accessibility. Second, according to my interpretation of conformance requirement 4, and the definitions of ‘accessibility supported’ and ‘relied upon, if javascript is implemented in a way that is accessibility supported and this content is ‘relied upon’ for conformance, then the same content must also conform if javascript is ‘turned off or is not supported’. (See http://www.w3.org/TR/2008/REC-WCAG20-20081211/#cc4, http://www.w3.org/TR/2008/REC-WCAG20-20081211/#accessibility-supporteddef, http://www.w3.org/TR/2008/REC-WCAG20-20081211/#reliedupondef) It seems to me that part of the problem(s) addressed in this thread lurks in the precision of the definition of 'accessibility supported'. Is it, for example, appropriate to deduce from this that the absence of support (i.e., due to age or sophistication or even malfunction) for a particular technology in a given user agent means that content cannot be relied upon to conform regardless of whether that technology is implemented in ways that are accessibility supported in other user agents? The list's thoughts about accessibility supported would be instructive ...

You're right, it's easy to create a website with CSS and HTML alone. not JavaScript. But an operating system is software that that drives hardware, and hardware does nothing without electricity. It's not possible for an operating system to do anything without power. It would be like trying to drive a car without gas and a motor. You can certainly power up a computer without an OS, those of us whole build computers do it all the time. But you can't get the computer to do anything useful until you install and OS (operating system).
