CSS Floating Label with Chrome Autofill Fix

The bug every login form ships with: Chrome autofills the email and the label crashes straight through the yellow text. This demo adds :autofill / :-webkit-autofill to the float selector so browser-filled values lift the label exactly like typed ones — and restyles the autofill highlight to match your theme. Variation: instead of shrinking in place, the label ESCAPES the field and docks above its top-left corner with spread letter-spacing — an eyebrow label.

## JavaScript
```js
/* No JavaScript — :autofill and :-webkit-autofill (in separate rules) join the float selector so browser-autofilled values lift the label; an inset box-shadow re-skins Chrome's yellow autofill wash. */
```

How this works

Standard CSS-only floating labels float on :focus and :not(:placeholder-shown) — but when Chrome or Safari autofills a field, some engines don't immediately treat the value as user text, so :placeholder-shown can still match and the label overlaps the autofilled value. The fix is to add :autofill (and the :-webkit-autofill prefix, kept as a separate rule so an unsupported selector doesn't invalidate the whole list) to the float condition.

The demo also neutralises the default pale-yellow autofill wash using the classic box-shadow: 0 0 0 1000px <bg> inset trick plus -webkit-text-fill-color, so autofilled fields look native to your design instead of Chrome's.

Techniques used: :autofill · :-webkit-autofill (separate rule so an unknown selector cannot kill the list) · inset box-shadow autofill re-skin · -webkit-text-fill-color · caret-color · the transition:background-color 99999s stall trick · :placeholder-shown float base · negative-translate escape float · letter-spacing transition

Make it yours

  • Change the autofill fill colour via the inset box-shadow colour.
  • Match autofilled text colour with -webkit-text-fill-color.
  • Use the Fill demo button to simulate autofill and watch the label lift.
  • Recolour focus/float through --accent.

Gotchas — read before shipping

  • Write :-webkit-autofill selectors in their OWN rule — a browser that doesn't recognise a selector drops the entire selector list, silently killing your float.
  • You can't remove Chrome's autofill background with background-color; only the inset box-shadow overlay works.
  • Test with real browser autofill (saved addresses), not just typing — they hit different pseudo-classes.

Floor set by oklch() as this demo is written. The core technique itself goes back further — Chrome 108+ (:autofill), all (-webkit-autofill).

Ship both the standard :autofill rule and a separate -webkit-autofill rule. The float still works everywhere via :placeholder-shown; autofill support is additive.
