Tailwind Material Design Outlined Text Field

The Google-style outlined field: on focus the label glides up onto the border and the outline 'opens' a notch around it. The notch is the label's own bg-white px-[5px] erasing the border behind it — no fieldset, no legend, no JS measuring. Focus thickens the edge with focus:shadow-[inset_0_0_0_1px_…], so the text never shifts.

What changed in the port

Which parts became utilities, which stayed CSS, and why.

  • --surface became plain bg-white on both card and label — the dependency is now visible side by side in the markup.
  • The row's grid-template-columns:1fr 1fr became grid grid-cols-2 gap-4.
  • UI upgrade — bug fix: the original's hover colour #a29bc was a five-digit hex, which browsers reject, so hover did nothing; it is now a valid --color-tfl09-line-hover token.
  • UI upgrade: card fields use tabular-nums with light tracking and sensible maxlengths, the header gained an 'Encrypted' trust cue, and the resting label rose from #756e8c (4.6:1) to 6.3:1.

How this works

The notch is a background, not a cut. The floated label paints the card's colour behind its text and pads it sideways, so the border line under it disappears — at any radius, for any label length.

<label class="absolute left-3 top-1/2 -translate-y-1/2 bg-white px-[5px]
  peer-focus:translate-y-[calc(-50%_-_28px)] peer-focus:scale-76 …">

Why shadow, not border-width. Going from 1.5px to 2.5px border moves the text 1px; an inset shadow thickens the edge visually with no box change.

Make it yours

  • The label background must match the surface — change bg-white on card and label together.
  • Notch padding: px-[5px].
  • Any radius works — try rounded-full on single-line fields.
  • Focus edge: the inset shadow's spread (1px).

Gotchas — read before shipping

  • On gradient or image surfaces the flat label background gives the trick away — use a solid chip instead.
  • Keep the floated label ≥12px computed (16 × 0.76 = 12.2px).
  • inputmode="numeric" + autocomplete="cc-*" matter more than any styling on payment fields.
