Password Input with Show/Hide Toggle and Floating Label

The login-form workhorse: a floating label password field with an in-field visibility toggle that swaps type between password and text — the eye button is a real <button> with aria-pressed and a dynamic label, sized 44px for touch, and positioned so it never collides with the floating label or the value. Variation: a SPRINGY float — an overshoot cubic-bezier makes the label bounce past its floated position and settle, adding play without a single keyframe.

## JavaScript
```js
(() => {
  const input = document.querySelector('#flb-15-pass');
  const btn = document.querySelector('#flb-15-toggle');
  btn.addEventListener('click', () => {
    const show = input.type === 'password';
    input.type = show ? 'text' : 'password';
    btn.setAttribute('aria-pressed', String(show));
    btn.setAttribute('aria-label', show ? 'Hide password' : 'Show password');
  });
})();
```

How this works

The toggle is the one floating-label job CSS can't do alone: swapping type="password" ⇄ type="text" requires DOM access. The JS here is eight lines — one click handler per field that flips the type, toggles aria-pressed, and updates the button's aria-label between 'Show password' and 'Hide password'. No keystroke listeners, so INP cost is zero during typing.

Layout-wise the input reserves right padding for the 44×44px button, the floating label floats up-left of it, and the eye/eye-off icons are two overlaid SVGs cross-faded by the button's aria-pressed state — CSS handles all the visuals; JS only flips state. A strength meter styled from the field's data-strength attribute shows how to extend the pattern.

Techniques used: type=password/text swap (the one JS line) · aria-pressed + aria-controls + live aria-label · CSS attribute-selector icon swap ([aria-pressed="true"]) · overshoot cubic-bezier(.3,1.8,.4,.9) springy float · 40px+ touch-target button inside the field · focus({preventScroll}) return

Make it yours

  • The toggle button is 44×44 — keep it; shrink only the icon inside.
  • Swap the SVG pair for your icon set (both are stroke=currentColor).
  • Delete the strength meter row if you only need show/hide.
  • Recolour via --accent; the meter's steps live in the [data-strength] rules.

Gotchas — read before shipping

  • The toggle must be a real <button type="button"> — a clickable div is invisible to keyboards and screen readers, and a missing type submits the form.
  • Use aria-pressed + a changing aria-label so AT announces the current state, and don't move focus on toggle.
  • Keep autocomplete="current-password" so password managers still fill the field after type swaps.
  • Never disable paste on password fields — it breaks password managers and helps no one.

Floor set by oklch() as this demo is written. The core technique itself goes back further — Chrome all.

One click listener; everything visual is CSS. Works with password managers — type swapping doesn't break autofill when autocomplete attributes are correct.
