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.
Lightweight & expandable
Modular, flexible, and ultra-efficient, its plugin architecture keeps the core engine tight while allowing virtually any feature to be added via optional plugins. GSAP 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.
