How to css clip-path browser support and fallbacks in 2026
- Step 1Check support for your shape type — polygon(), circle(), ellipse(), and inset() have 97%+ support. path() for arbitrary curves has 94%+ support (missing older Safari). Decide if the 6% missing path() support needs a fallback in your project.
- Step 2Write the fallback — Use @supports to provide a simpler fallback for unsupported browsers: @supports not (clip-path: path('M0,0')) { .hero { border-radius: 0 0 50px 50px } }. The fallback uses a simpler visual treatment that doesn't require path().
- Step 3Test in real browsers — Test clip-path behaviour in Chrome, Firefox, Safari (macOS and iOS), and Edge. Pay particular attention to Safari on iOS — clip-path on fixed-position elements has known bugs in certain iOS versions.
Frequently asked questions
Does clip-path work on position: fixed elements?+
Inconsistently. In Safari on iOS, clip-path applied to fixed-position elements can cause rendering bugs where the clip doesn't update during scroll. Workaround: apply clip-path to the content inside the fixed element rather than the fixed element itself, or use overflow: hidden as an alternative.
Is there a clip-path polyfill for older browsers?+
No well-maintained polyfill exists for clip-path in 2026, and one is rarely needed given 97%+ global support. For critical shape effects in older browsers, use SVG with clipPath elements as a progressive enhancement, or use simple box-shadow and border-radius for the fallback experience.
Does clip-path work inside CSS Grid or Flexbox containers?+
Yes. clip-path works inside any layout context. The clip is applied after layout is complete, so it doesn't affect how the element occupies space in the grid or flex container. The element's layout box remains unchanged — only the visible paint region is clipped.
What is the difference between clip-path: none and clip-path: unset?+
clip-path: none explicitly removes any clip path, leaving the element fully visible. clip-path: unset reverts to the inherited value (which is typically none, since clip-path does not inherit). In practice they behave the same unless a parent has set clip-path to a non-none value via the cascade.
