Great work, everyone! I should have expected this one to fall pretty quickly, as it's a common term, and indeed it has. And to think, I had so many cheesy clues up my sleeve.
The answer was indeed "responsive design", and I think, to be fair, I should declare two winners here, firstly @stautem, for getting it (but with the extra word), and also @micreate, who got the exact term I was looking for.
So congratulations to you both! We will be in touch shortly.
Thanks to everyone for your entries. "reserve meet" and "satisfaction" were indeed two translations that appeared after jumping through multiple languages. Who'd be a translator, eh? Anyhow, I'll try to post another one of these soon.
