Progressive enhancement and accessibility redux - QuirksBlog

This is a really interesting take on the intersection between accessibility and progressive enhancement (which I always felt was there, but this expresses it well):

Accessibility aims to optimize an experience across a spectrum of user capabilities. Progressive enhancement aims to optimize an experience across a spectrum of user agent capabilities.

Indeed, if you broaden the definition of “user agent” to include a user’s physiology, I think the concepts become nearly identical.

Ultimately you can’t control when and how things go wrong but you do have some control over what happens. This is why progressive enhancement exists.

And this is why user-agent sniffing not a future-friendly technique. A new mobile browser comes along, and it has to spoof a fake UA string to all of these sites.

It’s a Red Queen arms race.
