Tailwind Neumorphic Bottom Navigation Bar

A soft-UI fitness app on #e0e5ec: raised cards, recessed wells, and a bottom bar whose active tab presses into the surface. Every shadow pair is a --shadow-tmn16-* theme token, so shadow-tmn16-up and shadow-tmn16-in are the whole design language. Zero JavaScript.

What changed in the port

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

  • Six hand-repeated shadow pairs became four --shadow-tmn16-* theme tokens; every card, well, button and tab now uses shadow-tmn16-up, -up-sm, -in or -in-sm.
  • Fourteen inline style="…" attributes on the streak row and avatar became utilities.
  • UI upgrade from the CSS original: muted text rose from #8899aa (2.6:1) to #5f6b7a (5.0:1) and the four accents were deepened to pass 4.5:1 as tab labels; the daily goal gained a conic progress ring.
  • UI upgrade: emoji became stroke icons, the streak row is labelled by weekday, workout icons are labelled buttons that press in on tap, and tab hit-areas are 64×56px.

Demo: Tailwind Neumorphic Bottom Navigation Bar
Source: https://codefronts.com/navigation/tailwind-css-mobile-navbar/tailwind-neumorphic-bottom-navigation-bar/

A soft-UI fitness app on #e0e5ec: raised cards, recessed wells, and a bottom bar whose active tab presses into the surface. Every shadow pair is a --shadow-tmn16-* theme token, so shadow-tmn16-up and shadow-tmn16-in are the whole design language. Zero JavaScript.

How this works

Two shadows, one surface. Neumorphism is a light shadow up-left and a dark shadow down-right, both derived from the base colour. Declared as theme tokens they become utilities:

--shadow-tmn16-up: 6px 6px 14px var(--color-tmn16-dark), -6px -6px 14px var(--color-tmn16-light);
--shadow-tmn16-in: inset 4px 4px 10px var(--color-tmn16-dark), inset -4px -4px 10px var(--color-tmn16-light);

Tabs. Four radios; each page fades up via group-has-[#tmn-16-tN:checked]:, and the matching label swaps shadow-none for shadow-tmn16-in and picks up its accent colour.

Make it yours

  • New base colour: edit --color-tmn16-bg, then tune --color-tmn16-light (lighter) and --color-tmn16-dark (darker) to match.
  • Deeper relief: raise offsets/blur in the shadow tokens.
  • Neumorphic bar: give the nav shadow-tmn16-up and inset it with mx-4 mb-4 rounded-3xl.
  • Single accent: replace the four per-tab colours with text-tmn16-acc.

Gotchas — read before shipping

  • Element and page backgrounds must match exactly — any difference breaks the illusion.
  • Neumorphism is low-contrast by nature; text must carry the hierarchy — muted copy here is 5.0:1, not the original's 2.6:1.
  • On dark or saturated bases the light shadow disappears; this language belongs to mid-light greys.
