How do I animate multiple SVG paths in sync?

Store lengths in CSS variables and trigger animations with animation-delay. In JavaScript, build a timeline using GSAP or Anime.js.

Is SMIL still supported for SVG path animation?

Modern browsers still support SMIL. Use the animate element for portable graphics or fallback scenarios, and provide alternatives where necessary.

SVG Path Animation Tutorial: Master Stroke and Morph Techniques

Drawing and morphing vector paths is the backbone of most SVG animations. In this tutorial you’ll learn how to reveal strokes, move objects along curves, and morph shapes without breaking performance budgets. If you need the broader context—including tooling and accessibility tips—start with the SVG Animation Guide and then follow the hands-on steps below.

1. Understand Path Metrics

Before animating, measure your path length so you can calculate dash arrays, offsets, or timeline values.

const path = document.querySelector('#signature')
const length = path.getTotalLength()
console.log(length) // e.g. 482.6

Use that value to set stroke-dasharray and stroke-dashoffset for drawing effects.

2. Create a Line-Drawing Reveal with CSS

CSS-only motion keeps bundles small and works perfectly for hero illustrations or signatures. Pair this with the deeper tactics in SVG Animation with CSS.

<svg viewBox="0 0 320 120">
  <path id="signature"
        d="M10 80 Q60 10 120 70 T230 60 L310 90"
        fill="none" stroke="#2563eb" stroke-width="6" />
</svg>

<style>
  #signature {
    stroke-dasharray: 482.6;
    stroke-dashoffset: 482.6;
    animation: draw 2.4s ease-in-out forwards;
  }

  @keyframes draw {
    to { stroke-dashoffset: 0; }
  }
</style>

Optimization tips

Use stroke-linecap="round" for smoother reveals.
Set animation-fill-mode: forwards to preserve the final state.
Add prefers-reduced-motion fallbacks for accessibility.

3. Move Objects Along a Path (WAAPI Example)

<svg viewBox="0 0 200 200">
  <path id="orbit" d="M100,20 A80,80 0 1,1 99.9,20" fill="none" />
  <circle id="satellite" r="6" fill="#f97316" />
</svg>

<script>
const motionPath = document.querySelector('#orbit')
const target = document.querySelector('#satellite')

target.animate(
  [
    { offsetDistance: '0%' },
    { offsetDistance: '100%' }
  ],
  {
    duration: 4000,
    iterations: Infinity,
    easing: 'linear'
  }
)
</script>

For broader browser support, polyfill WAAPI or use GSAP’s MotionPathPlugin. When you need a quick prototype, drop the path and asset into the SVG animation tool and export the timeline.

Tip: When handing assets to developers, include a link to the Animate SVG preview and note which segments rely on easing tokens so the implementation matches your intent.

Layered Path Animation Techniques

Not every animation targets a single stroke. Complex illustrations often include overlapping paths that animate together. Start by grouping related elements and defining CSS custom properties for their lengths. With those tokens, you can orchestrate waves, city skylines, or multi-step signatures. The SVG animation tool lets you preview layered sequences and export per-layer keyframes so you can reassemble them in code.

Coordinated Reveal

:root {
  --roof-length: 240;
  --wall-length: 320;
}
.house-roof {
  stroke-dasharray: var(--roof-length);
  stroke-dashoffset: var(--roof-length);
  animation: drawRoof 1.2s ease-out forwards;
}
.house-walls {
  stroke-dasharray: var(--wall-length);
  stroke-dashoffset: var(--wall-length);
  animation: drawWalls 1.6s ease-out 0.3s forwards;
}
@keyframes drawRoof { to { stroke-dashoffset: 0; } }
@keyframes drawWalls { to { stroke-dashoffset: 0; } }

Use delays to avoid overwhelming the eye and to maintain timing consistency across devices. If you need to speed up the entire sequence, adjust the duration token in one place instead of editing every keyframe.

Advanced Path Manipulation

Beyond basic reveals, path animations excel at rerouting objects along curves and morphing between complex shapes. Combine offset-path with CSS variables to let JavaScript or user gestures influence motion.

.ball {
  offset-path: path('M10 120 Q80 20 150 120');
  animation: roll 2s cubic-bezier(.22,.61,.36,1) infinite alternate;
}
@keyframes roll {
  from { offset-distance: 0%; }
  to { offset-distance: 100%; }
}

To make the animation interactive, update offset-distance with JavaScript inside a pointermove handler or hook it to scroll progress. When you need more control, export the motion from our Animate SVG workspace as JSON and feed it into GSAP’s MotionPathPlugin. For morphing, keep a library of normalized shapes in a dedicated folder. Use CLI tools such as svgo with the convertPathData plugin to reduce points before bringing them into your timeline. Store version numbers in the filename (logo-outline.v2.svg) so you know which path the development team implemented.

Testing & Debugging Checklist

Use this quick checklist before handing off final assets:

[ ] Run getTotalLength() on every animated path to ensure no zero-length segments remain.
[ ] In DevTools Elements panel, toggle the .paused class to confirm animations stop gracefully.
[ ] Test prefers-reduced-motion on desktop and mobile simulators. Provide a static fallback or shortened animation that communicates the same information.
[ ] Validate on low-powered devices (throttled CPU) to ensure layered reveals do not stutter.
[ ] Re-export timelines from the SVG animation tool if easing tokens change late in the cycle.

Document findings in your motion log so repeated issues (like mismatched lengths or forgotten fallbacks) are caught earlier in future projects.

4. Morph Between Shapes

Morphing requires paths with matching point counts. Use SVGator, Illustrator, or our generator to normalize shapes, or script the process with flubber.

import { gsap } from "gsap"
import { MorphSVGPlugin } from "gsap/MorphSVGPlugin"
gsap.registerPlugin(MorphSVGPlugin)

gsap.to("#logo-path", {
  duration: 1.6,
  morphSVG: "#logo-outline",
  repeat: -1,
  yoyo: true,
  ease: "power1.inOut"
})

Quality checklist

Match direction (clockwise vs counter-clockwise) for smoother interpolation.
Keep point counts under 200 for performance.
Blend morphing with opacity or blur to hide point-by-point differences.

5. Test and Iterate

Use DevTools to inspect stroke-dashoffset and computed transforms.
Run SVGO to remove redundant commands.
Validate accessibility and timing with the How to Check SVG Animation guide.
Compare final motion with examples from SVG Animation Examples.

Path Animation Checklist

[ ] Normalize paths (point count & direction)
[ ] Measure length and store in CSS variables for reuse
[ ] Add prefers-reduced-motion fallbacks
[ ] Keep animation durations between 0.6s and 3s for legibility
[ ] Test morphs on low-powered devices

Real-World Use Cases

Product tours: Animate arrows and highlights along onboarding flows; export a variant for every screen size from the SVG animation maker.
Data dashboards: Draw trendlines and threshold markers on load; trigger morphs when filters change.
Storytelling graphics: Morph illustrations between seasons or time periods in editorial pieces, keeping text accessible by layering live HTML over the animated SVG.

FAQ

Can I animate paths in CSS only?
Yes. Stroke reveals and simple transforms work great with CSS. For complex morphs, use JS or SMIL. What’s the best way to animate text outlines?
Convert text to paths, combine shapes, and apply the same dash technique. Ensure you keep live text for accessibility elsewhere on the page. How do I animate multiple paths in sync?
Store lengths in CSS variables and trigger animations with animation-delay. In JS, build a timeline (GSAP, Anime.js) to coordinate. Is SMIL dead?
No—modern browsers still support it. Use <animate> for portable graphics or fallback scenarios. How do I keep path animations responsive?
Use percentage-based coordinates, wrap SVGs in responsive containers, and update motion values with CSS variables or JavaScript when the viewport changes.
