Responsive Layout Grid for 3D Configurators

Standard viewport layout behaviors across desktop, tablet, and mobile dimensions, optimized for screen conservation.
Published: 7/20/2026

Interactive 3D configurators must fit exactly within the viewport without triggering native browser window scrolls. Because mobile address bars dynamically expand and contract, traditional CSS height metrics like 100vh cause layout shifts and hidden buttons. The interface must use strict height constraints to stay locked at 100% viewport height.

  • Root Height Model: The root wrapper must use dynamic viewport heights (e.g. h-[100svh] or h-[100dvh]) paired with overflow-hidden to prevent browser-level bounce scrolling.
  • Split-Screen Grid: Implement a flex container that is flex-col on mobile and flex-row on desktop (min-width: 768px).
  • Mobile Viewport Budget: Restrict the 3D viewport canvas to a fixed top section (40vh to 48vh). This leaves the remaining height (52vh to 60vh) for configuration panels.
  • Mobile Step Headers: Position the step/tab navigation bar at the top of the mobile bottom-panel (block md:hidden border-b), acting as the dividing line between 3D and 2D elements.
  • Internal Panel Scroll: Option panel elements must use flex-1 with overflow-y-auto and condensed vertical padding. This guarantees option cards and swatches remain visible without squishing.
  • Absolute Overlay Controls: Floating viewport utilities (camera resets, material swatches) must float absolutely inside the viewport container rather than occupying grid tracks.
