Learn how to make a simple play / pause toggle button to control any GSAP animation (tweens or timelines). Same concepts apply to toggling the reversed() state of an animation too.

The secret to building gorgeous sequences with precise timing is understanding the super-flexible "position" parameter which controls the placement of your tweens, labels, callbacks, pauses, and even nested timelines.

Responsive animation just got easier with GSAP 1.13.1 and support for percent-based translations. Plus enhanced support for RequireJS, AMD, Browserify and one less reason to use jQuery.

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. You'll see exactly where some of the pain points are for a typical project and how they can bring your workflow to a grinding halt.

Why has GSAP become an industry standard for animation on the web? Here are a few of the practical, real-world reasons.

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).

This video walks you through some common problems that professional animators face every day and shows you how GSAP’s TimelineLite tackles these challenges with ease.
