```How this works
Glass is not a translucent rectangle — it needs a blurred backdrop, a directional rim and a subtle internal gradient, all three:
.cb-23__btn{
background:linear-gradient(150deg,
color-mix(in srgb,white 26%,transparent),
color-mix(in srgb,white 8%,transparent));
backdrop-filter:blur(16px) saturate(1.5) brightness(1.06);
box-shadow:
inset 1px 1px 0 rgba(255,255,255,.65), /* lit edge */
inset -1px -1px 0 rgba(255,255,255,.18), /* far edge */
0 18px 40px -18px rgba(6,18,30,.6);
}The frost is two large, very soft radial gradients pinned to opposite corners, plus a fine speckle layer — ice reads as uneven, so a uniform white overlay always looks like plastic. The crack is a clip-path polyline drawn as a 1px white line that scales in on :active and fades:
.cb-23__btn:active .cb-23__crack{ animation:cb-23-crack .5s ease-out; }The background photograph is a lazily-loaded Unsplash image with a flat fallback colour behind it, so a network failure leaves a solid dark surface and the glass still reads correctly.
Make it yours
- Tune the frost with the blur radius and the two corner gradients; heavier blur reads colder, lighter reads like wet glass.
- Swap the photo for your own — the glass adapts to any backdrop because it blurs whatever is behind it.
- Drop
saturate()for a neutral frost, or raise it to 1.8 for a tropical, colour-bleeding look. - For a fully opaque fallback, put a 60%-white background under the blur in the
@supports notblock (already wired).
Gotchas — read before shipping
backdrop-filterneeds something behind it: over a solid page colour it does nothing at all.- Text on glass is the number-one contrast failure. This demo keeps a dark scrim behind the label; verify against the lightest part of your image.
backdrop-filtercreates a containing block and forces a new compositing layer — expensive at large sizes and unusable behind position:fixed children.- Safari historically requires
-webkit-backdrop-filter; both are declared here. - Never animate the blur radius: it re-rasterises the backdrop every frame. Animate opacity or a separate overlay instead.
Browser support
| Chrome | Safari | Firefox | Edge |
|---|---|---|---|
| 76+ | 9+ (prefixed) | 103+ | 76+ |
backdrop-filter: Chrome 76 / Safari 9 with -webkit- / Firefox 103. The @supports not block supplies a solid translucent fallback, so unsupported engines still get a legible button.
