Tailwind Split-Screen Sidebar Category Navigation

A two-pane shop layout: a 104px category rail with an active edge indicator, and a content panel that fades and slides as you switch. The whole phone re-tints per category — violet, green, red, blue — with a colour transition the original could not animate. Zero JavaScript.

What changed in the port

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

  • Twelve #c:checked ~ .left label[for] … rules became per-label group-has-[#tmn-14-cN:checked]: utilities; the per-panel gradient rules moved onto each panel as bg-linear-160.
  • The unused .mn-14__toggle-btn rule in the original was dropped.
  • UI upgrade from the CSS original: the rail now cross-fades between solid category tints (gradients snapped), product cards gained gradient artwork and labelled 36px add-to-bag buttons, and each panel shows an item count.
  • UI upgrade: label text rose from white/40 (3.4:1) to white/55 (5.1:1), secondary copy from white/40 to white/60, and the radio group is keyboard-operable with a visible focus wash.

Demo: Tailwind Split-Screen Sidebar Category Navigation
Source: https://codefronts.com/navigation/tailwind-css-mobile-navbar/tailwind-split-screen-sidebar-category-navigation/

A two-pane shop layout: a 104px category rail with an active edge indicator, and a content panel that fades and slides as you switch. The whole phone re-tints per category &mdash; violet, green, red, blue &mdash; with a colour transition the original could not animate. Zero JavaScript.

How this works

One radio set, two panes. Four sr-only radios at the top of the phone; the rail's labels and the right-hand panels all read them via group-has-[#tmn-14-cN:checked]:.

<aside class="bg-tmn14-c1-rail transition-colors duration-500
  group-has-[#tmn-14-c2:checked]:bg-tmn14-c2-rail …">

Why solid colours. The original swapped linear-gradient backgrounds, which cannot interpolate, so the rail snapped. Solid tokens cross-fade; the panel gradient stays per panel and arrives with the panel's own fade.

Make it yours

  • Wider rail: change w-26 on the aside and left-26 on the content.
  • Icon-only rail: hide the label text and narrow to w-18.
  • Full-row highlight: replace the indicator with group-has-[…]:bg-white/8 on the label.
  • More categories: add a radio, a label and a panel; the rail scrolls.

Gotchas — read before shipping

  • Radio names must match, and every panel must reference its own id.
  • Inactive panels stay in the DOM — they're invisible, so their buttons are not tab stops.
  • Keep tints dark enough for text-white/90 — each rail token holds 12:1 or more.
