Historically Bootstrap has been desktop-first—since the initial release and every subsequent update. With the upcoming release of v3, we've switched to a mobile-first approach. We're still finalizing much of the CSS, but the last few months of development have been intense and an awesome learning experience. This talk highlights some of the things I've learned along the way—some design, some code, and some still unanswered questions.
