Can GSAP be built on top of the Web Animations API (WAAPI)? Probably not. Here's why.
Why doesn't GreenSock use a more common open source license like MIT? Find out here.
HTML5 has unique strengths that allow us to move beyond the simplistic "aggregate total file size" mentality of yesteryear. We need to look at kilobyte cost in a new way, especially for banner ads.
The sudden and rather violent shift away from Flash in the banner ad industry has designers and developers scrambling. We've got answers. Welcome to the HTML5 era.
The GSAP 1.16.x update delivers some nifty new features like svgOrigin as well as a better-than-ever Draggable that has autoScroll capabilities, a new method for determining the drag direction, and more.

There are some interesting (and surprising) performance implications of using CSS animations that aren't widely known. Check out this video demonstration.
People are switching to GSAP in droves, and here are a few of the practical, real-world reasons why.
With the release of iOS 7, I was anticipating some big leaps forward in browser performance. What I found was quite surprising. Is anyone else experiencing the same thing? Here's a quick [and very casual] video showing what I discovered:
Making a DOM element draggable isn't terribly difficult - there are jQuery plugins and even some native HTML5 capabilities in newer browsers. But generic dragging is kinda boring. What about smooth, natural momentum-based continuation after the user releases the mouse (or touch on mobile devices)? What about imposing bounds and edge resistance and silky-smooth redirection to certain landing values that you provide? Or flick/drag scrolling with bounce-back that doesn't look awkward? Or instead of dragging to change the position of an element, what if you want to spin it? Maybe you even want to track the momentum and let it come to rest naturally or rig it to glide to a stop at a certain value, Wheel-of-Fortune style? Yeah, that's a lot more complex. In fact, it can be a real drag to build (sorry, the pun was irresistible).
