3D Flip Canvas Mobile Hamburger Navigation CSS

The theatrical finale: open the menu and the entire page tilts back in 3D — rotateY around its right edge with real perspective — swinging aside like a door to reveal the nav standing behind it, whose links counter-rotate into place from the opposite angle. Three properties (perspective, transform-origin, preserve-3d) produce the drama; the layering discipline of demo 08 keeps it usable. The push menu's flamboyant sibling, for portfolios that want an entrance.

How this works

3D in CSS needs a camera before anything rotates — that's perspective on the PARENT (distance from viewer to canvas; smaller = fisheye):

.viewport{ perspective:1400px; overflow:hidden; }
.canvas{ transform-origin: 88% 50%;        /* hinge near right edge */
  transition: transform .6s cubic-bezier(.4,0,.2,1); }
[data-open] .canvas{
  transform: translateX(-58%) rotateY(34deg) scale(.92); }

Write these as ONE transform string, not individual translate/rotate properties — the individual properties apply in a fixed order (translate→rotate→scale) which is what you want here, but the hinge illusion depends on translation and rotation being tuned as a pair; keeping them in one declaration makes that coupling explicit and editable. The transform-origin off-center is the trick that reads as a door instead of a spin: the right edge nearly stays put while the left edge sweeps toward the viewer.

The menu behind gets counter-motion: it starts at rotateY(18deg) translateX(40px) (angled the opposite way, as if you're looking down a corridor) and settles flat with staggered per-link delays. Both planes moving in opposite rotations is what sells depth — one static layer + one rotating layer reads as a flat slide with a skew glitch.

Discipline from demo 08 still governs: the tilted canvas gets inert (its buttons are visually 3D but functionally reachable otherwise), a click-catcher covers it for tap-to-close, Escape restores, and the deep shadow under the lifted edge (one box-shadow that fades in with the transform) grounds the whole move physically. Under prefers-reduced-motion the rotation is dropped entirely and the pattern degrades to demo 08's flat push — motion is the garnish, never the mechanism.

Make it yours

  • Drama dial: perspective 1400px (subtle) → 900px (theatrical) → 600px (funhouse). Tune with rotateY together; big angle + short perspective clips the canvas edge off-viewport.
  • Hinge side: origin 88% + negative translateX swings left (shipped); mirror the three signs for a right swing. Top-hinged (origin 50% 0 + rotateX) gives the 'falling card' variant.
  • The menu corridor angle (-18deg) and its settle are independent of the canvas move — flatten it to 0 for a calmer backdrop, or deepen to -30deg with a longer delay for maximum parallax.
  • Content on the canvas can layer in 3D too: give a hero card translateZ(30px) (needs transform-style:preserve-3d on the canvas) and it floats above the tilting page.

Gotchas — read before shipping

  • perspective goes on the PARENT of the transformed element — perspective on the canvas itself (or the perspective() function inside its own transform) computes per-element and kills the shared vanishing point the scene needs.
  • overflow:hidden on the viewport clips the swinging edge as it comes toward the viewer — intentional here (it's a stage); on a full page use overflow:clip on html,body or the page grows scrollbars mid-swing.
  • Text on a rotated plane rasterizes in some engines mid-transition (momentary blur) — keep body text OFF the moving canvas or accept the 600ms shimmer; the skeleton content here sidesteps it.
  • A transformed canvas is a containing block: position:fixed children (toasts, FABs) ride the rotation. Portal them outside the canvas — the same trap as demos 04/08, at triple the visibility.

CSS 3D transforms + perspective are universal since 2013; inert (Chrome 102/Safari 15.5/Firefox 112) is the newest dependency. oklch() sets the stated floor.
