Tailwind Full-Height Flexbox Sidebar Layout

The canonical app layout, done right: a flex flex-col sidebar where the link region takes flex-1 min-h-0 overflow-y-auto, pinning the brand to the top and the storage card plus user footer to the bottom — no absolute positioning, and long menus scroll inside the middle region instead of pushing the footer off-screen.

What changed in the port

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

  • The flex column survived intact as utilities; the unused .spacer rule was dropped and per-link margin-bottom became gap-0.5.
  • UI upgrade from the CSS original: the link region is min-h-0 overflow-y-auto, so a long menu scrolls instead of pushing the footer off-screen (the original's own gotcha, now fixed), and the nav is sticky h-svh.
  • UI upgrade: the storage note became a real meter with a fill bar, the ↗ glyph became a labelled 44px Sign-out <button>, and toolbar buttons gained icons and focus rings.
  • UI upgrade: the section labels went from #57534e on near-black (2.4:1) to #8f8984 (5.3:1).

How this works

Three children, one grows. The brand and the footer size to their content; the link region claims everything else:

<nav class="flex h-svh flex-col">
  <div>brand</div>
  <div class="min-h-0 flex-1 overflow-y-auto">links</div>
  <div>storage + user</div>

min-h-0 is the fix most sidebars miss. Flex items default to min-height:auto, so a long link list refuses to shrink and shoves the footer out of view. Setting it to zero lets overflow-y-auto take over.

The storage meter is a role="meter" with aria-valuenow, filled by a w-[68%] bar.

Make it yours

  • Bottom-anchored secondary group: move Members/Roles into the footer block above the user row.
  • Resizable: expose w-60 as w-(--nav-w) and update the property from a drag handle.
  • Light sidebar: swap bg-tsm08-nav for bg-white border-r and the nav tokens for dark ink.
  • Storage level: edit w-[68%] and aria-valuenow together.

Gotchas — read before shipping

  • Without min-h-0 on the scrolling flex child, overflow-y-auto never activates.
  • Use h-svh, not h-screen, on mobile — 100vh includes the collapsing browser toolbar and hides the footer.
  • Icon-only buttons (sign out) need an accessible name: aria-label or sr-only text.

Browser support

Flexbox and svh units (Chrome 108 / Safari 15.4 / Firefox 101) are well supported; the floor is v4's own sheet.
