That’s right. Anything. No predefined list of properties to choose from. Any numeric property of any object can be tweened, and if the property needs special handling (like colors, filters, non-numeric values, etc.), chances are there’s a plugin that will do it. If not, one can be created. The possibilities are endless.
Modular, flexible, and ultra-efficient, its plugin architecture keeps the core engine tight while allowing virtually any feature to be added via optional plugins. TweenLite packs an amazing amount of power into a surprisingly small package.
The GSAP isn’t built on top of any 3rd party tools like jQuery (although it works great with jQuery). This approach minimizes load times and maximizes performance.
You’re not limited to “one-after-the-other” sequencing; have animations overlap as much as you want. Nest timelines inside other timelines. Insert gaps, callbacks, labels, staggered tweens, and more. You get precise control over timing and unprecedented flexibility to create expressive animations with minimal code.

Learn the basics of GSAP quickly. Includes plenty of videos and demos that will get you animating the web in no time.
With over 5 hours of HD video and a companion eBook with step-by-step instructions, this training will introduce you to the best of GSAP.
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.
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.
TweenMax extends TweenLite, adding many useful (but non-essential) features like repeat(), repeatDelay(), yoyo(), staggered tweens, and more. It also includes many extra tools and plugins by default, making it extremely full-featured (TweenLite, TimelineLite, TimelineMax, CSSPlugin, AttrPlugin, RoundPropsPlugin, DirectionalRotationPlugin, BezierPlugin, and EasePack).
TimelineLite is a lightweight, intuitive timeline class for building and managing sequences of TweenLite, TweenMax, TimelineLite, and/or TimelineMax instances. You can think of a TimelineLite instance like a container where you place tweens (or other timelines) over the course of time.
TimelineMax extends TimelineLite, offering exactly the same functionality plus useful (but non-essential) features like repeat, repeatDelay, yoyo, currentLabel(), tweenTo(), tweenFromTo(), getLabelAfter(), getLabelBefore(), getActive() and more.TimelineMax is GSAP's most powerful and feature-packed sequencing tool.
