Why GSAP and SVG are a powerful combo

Scalable Vector Graphics (SVG) unlock crisp, scalable visuals directly in the browser, while GSAP (GreenSock Animation Platform) offers a robust, high-performance animation engine. Together, they enable smooth, precise control over paths, shapes, fills, strokes, and transforms. If you’ve ever tried to morph a shape or animate a complex stroke with CSS alone, you know how quickly you hit browser quirks. GSAP abstracts those concerns with timeline-based control, pause/resume, easing, and reliable cross‑browser playback. For designers, this means you can experiment with motion design without leaning on heavy JavaScript frameworks. To see practical SVG tutorials, check out SvGenius resources.

Getting started: setup and a tiny SVG example

Start by adding GSAP to your project. You can use a CDN for quick experiments:

<script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.12.3/gsap.min.js"></script>

Then create a simple SVG and animate its attributes with GSAP. Here’s a concise example that animates a circle's radius and fill color.

<svg width="200" height="200" viewBox="0 0 200 200" xmlns="http://www.w3.org/2000/svg">
  <circle id="pulse" cx="100" cy="100" r="40" fill="#4caf50"/>
</svg>

<script>
  gsap.to("#pulse", { duration: 1.2, attr: { r: 70 }, fill: "#8e44ad", repeat: -1, yoyo: true, ease: "power1.inOut" });
</script>

This tiny snippet shows the core idea: animate SVG attributes directly, with GSAP handling timing and easing. For more SVG-specific payloads, see examples on SvGenius.

Animating paths and strokes: practical patterns

Paths are a favorite playground for GSAP. You can animate stroke-dasharray to simulate drawing, or morph shapes with the MorphSVGPlugin. While MorphSVGPlugin is a paid plugin, you can achieve many effects with GSAP’s core features and some clever SVG properties.

Example: drawing a path stroke as it appears on screen:

<svg width="400" height="120" viewBox="0 0 400 120" xmlns="http://www.w3.org/2000/svg">
  <path id="scribble" d="M20,100 C60,20 140,140 380,60" stroke="#1e88e5" fill="none" stroke-width="6" stroke-linecap="round"/>
</svg>

<script>
  const path = document.getElementById("scribble");
  const length = path.getTotalLength();
  path.style.strokeDasharray = length;
  path.style.strokeDashoffset = length;
  gsap.to(path, { duration: 2, strokeDashoffset: 0, ease: "power2.inOut" });
</script>

Key tips:

• Set strokeDasharray and strokeDashoffset to the path length for a clean draw animation.
• Consider masking or clipping for more complex reveals.
• Keep a baseline of motion with a simple timeline and add sub-animations for interactivity.

Timelines: coordinating multiple elements

Timelines are the heartbeat of GSAP. They let you orchestrate multiple animations with precise timing, staggering, and callbacks. This is especially useful when you’re animating groups of SVG elements, such as a logo or an icon set.

Simple multi-element timeline:

// Animate three SVG shapes in sequence
const tl = gsap.timeline({ defaults: { duration: 0.8, ease: "power2.inOut" } });

tl.from("#shape1", { y: -20, opacity: 0 })
  .from("#shape2", { x: 40, opacity: 0 }, "-=0.4")
  .from("#shape3", { rotation: 180, transformOrigin: "50% 50%" }, "-=0.5");

Using timelines helps you maintain a clean structure as your project grows. You can also pause, resume, or reverse the entire sequence with a single call, which is handy for interactive UI animations. For more advanced timeline techniques, visit SvGenius tutorials.

Performance considerations: smooth motion on any device

SVG animation with GSAP is typically performant, but a few best practices matter:

• Prefer transforms (translate/scale/rotate) over animating layout-affecting properties when possible.
• Use requestAnimationFrame-backed GSAP rendering and avoid heavy recalculations in every frame.
• Limit the number of simultaneously animating elements to prevent layout thrashing.
• Lazy-load or defer non-critical animations to reduce the initial render cost.

Accessibility and progressive enhancement

Animations should enhance, not hinder. Provide controls to pause or disable motion for users who prefer reduced motion. You can respect the system preference with CSS media queries and expose a simple toggle that updates GSAP timelines.

Simple respect-for-reduced-motion pattern:

@media (prefers-reduced-motion: reduce) {
  .gsap-anim { animation: none !important; transform: none !important; }
}
