Asymmetrical organic SVG section wave CSS

Non-repeating, hand-drawn-feeling curves for editorial and brand-showcase sites. Symmetry reads as template; asymmetry reads as art direction — these paths deliberately break the mirror so each section edge looks authored rather than generated.

## JavaScript
```js
/* No JavaScript — deliberately unequal control points give one dominant crest and a long quiet run-out. */

/* No JavaScript — the path is authored wider than its box and positioned to overflow both edges, so the shape reads as a fragment. */
```

How this works

An organic edge comes from unequal control points: one long lazy sweep, one tight pinch, and a flat run-out. Keep one dominant crest and let the rest be quiet — the same rule photographers use for composition.

<!-- long sweep, tight pinch, flat run-out -->
<path d="M0,88 C300,-6 520,96 760,72 C900,58 1080,80 1440,26 L1440,120 L0,120Z"/>

For a truly blobby edge, use a closed path shifted off the section's box so the curve continues past the viewport on one side only — the eye reads the shape as a fragment of something larger, which is what makes it feel organic instead of decorative.

Make it yours

  • Move a single control point 40px to break symmetry — that is usually enough.
  • Overflow the path on one side only for a fragment-of-a-larger-shape effect.
  • Pair with an off-centre headline so type and shape share the same asymmetry.
  • Add a thin stroked copy of the path in an accent colour as a hand-drawn outline.

Gotchas — read before shipping

  • Asymmetric paths distort unevenly when stretched — check 480px and 1920px.
  • Keep the deepest point away from where your copy sits.
  • Do not reuse the same asymmetric path in five places; it becomes a logo you did not intend.
  • Fill and section colour must match exactly, or the fragment reads as a mistake.
