Ultra high-performance, professional-grade animation for the modern web using javascript. The new standard for HTML5 animation.

FEATURES Crazy fast: Performance is paramount, especially on mobile devices with sluggish processors. Silky smooth animation is the hallmark of any tweening engine worth its weight and GSAP outperforms old “industry standards” by literally 1000%+ under stress. What was jerky and twitchy is now fluid. It’s the result of countless optimizations made to ensure that your interactive projects are responsive, efficient, and buttery smooth. Check out the speed test for a head-to-head comparison. Freakishly robust: Built for professionals, GSAP is packed with features that make most other engines look like cheap toys. Animate colors, beziers, css properties, arrays, scrolls and lots more. Round values, smoothly reverse() on the fly, use relative values, automatically accommodate getter/setter functions, employ virtually any easing equation, and manage conflicting tweens like a pro. Define callbacks, tween in seconds or frames, build sequences effortlessly (even with overlapping tweens), repeat/yoyo and more. Compatible: HTML5, jQuery, Canvas, CSS, new browsers, old browsers, RequireJS, EaselJS, mobile, and more – GSAP gets along with them famously. Use your favorite tools without jumping through endless hoops to ensure compatibility. It even accommodates various transforms (scale, skew, rotation, x, and y) in modern browsers plus IE back to version 6 without requiring clunky browser prefixes and hacks. We worry about compatibility so that you don’t need to. Another headache solved.
