PUBLIC MARKS from srcmax with tags animation & transform

I’ve come to love FLIP as a way of thinking about animations, because it’s a good match of JavaScript and CSS. Calculate in JavaScript, but let CSS handle the animations for you. You don’t have to use CSS to do the animations, though, you could just as easily use the Web Animations API or JavaScript itself, whatever’s easiest. The main point is that you’re reducing the per-frame complexity and cost (which normally means transform and opacity) to try and give the user the best possible experience.
