Progressive enhancement is an escalator that becomes stairs. Graceful degradation is building a lift,then having to add stairs. — Andrew Wight

I like an escalator because an escalator can never break, it can only become stairs. You would never see an ‘Escalator temporarily out of order’ sign, just an ‘Escalator temporarily stairs. Sorry for the convenience. We apologize for the fact that graceful#degradation you can still get up there.’ — Mitch Hedberg

There’s a common misconception that progressive enhancement means that you’ll spend your time dealing with older browsers, but in fact the opposite is true. Putting the basic functionality into place doesn’t take very long at all. And once you’ve done that, you’re free to spend all your time experimenting with the latest and greatest browser technologies, secure in the knowledge that even if they aren’t universally supported yet, that’s okay: you’ve already got your fallback in place. — Jeremy Keith

The key to thinking about web development this way is realising that there isn’t one final interface —there could be many, slightly different interfaces depending on the properties and capabilities of any particular user agent at any particular moment. And that’s okay. Websites do not need to look the same in every browser. — Jeremy Keith

Once you truly accept that, it’s an immensely liberating idea. Instead of spending your time trying to make websites look the same in wildly varying browsers, you can spend your time making sure that the core functionality of what you’re building works everywhere, while providing the best possible experience for more capable browsers. — Jeremy Keith
