Not sure if this question is a good fit for this forum, if not maybe some moderators can move it to StackOverflow.
Where should I be looking to make an accessible web site nowadays? I remember 10 years ago there was the WAI Initiative. Is that still documenting best practices and issuing recommendation towards making an accessible website? I mean I know they do have an updated website but is someone still considering their recommendation meaningful or has some other standard emerged out of the real world practices?
Or is accessibility nowadays about writing valid and semantically meaningful markup/css and applying micro-formats the way Wordpress does it?
