Apart from the “glow” ideas we last talked about with WordPress Blog TwentyTen Theme Glow Tutorial, that being the “what” of what we are doing, “where” are we applying it? Anyone, anyone? Yes, Casper Brindle, we’re differentiating “what” to do by device width.
And the “@” in CSS indicates a “rule”. So … yes, Casper Brindle? Indeed, they are called CSS @media Rules but no, Casper, it does not cover “Netflix After 10” rules, OK?
