We're excited to announce several new features in the GreenSock Animation Platform (GSAP) 1.12.0 that will increase not only "real" performance, but "perceived" performance as well. The innovative lagSmoothing() feature allows GSAP to automatically heal from CPU spikes that cause lag, all while maintaining perfect synchronization between all animations. And the new "lazy" rendering helps avoid layout thrashing when many animations start simultaneously.
I'm going to take a deeper look into CSS Animations and how they fit (or don't fit) into a modern animator's workflow. This isn't about simple fades or basic transitions (CSS is great for those); Developers who use animation to tell a story or deliver an incredibly rich interactive experience require a very different workflow than those who are simply doing UI transitions. 'm going to show you exactly where some of the pain points are for a typical project and how they can bring your workflow to a grinding halt. Even relatively simple animations like the one below can become surprisingly cumbersome with CSS.
