My experience is that Bootstrap makes 95% easier but the 5% that doesn't cooperate eats up all the savings of the 95%. When it doesn't do what you intend, it's a black box that usually ends up being "fixed" using obscure CSS or JavaScript fudges found on Stackoverflow etc. It feels like: "Just put in 'grf:snig;bleppo(){99.foo()}' here, and that should fix it."
