Responsive Controls

Design once.
Tune every breakpoint.

Independent overrides per device. Tune typography, spacing, and layout for phones, tablets, and desktops without leaving the canvas — and without writing a single media query.

One canvas, three views

Switch breakpoints without losing work

Make a change at one breakpoint, leave the others untouched. Or apply globally with a click.

Desktop, 1280px+

Full-width layouts, multi-column grids, sticky headers, and side-by-side hero compositions. The widest expression of your design.

Tablet, 768px

Auto-collapses 3-column grids to 2. Type scales down. Sticky elements unstick. Touch targets grow. All without touching CSS.

Mobile, 375px

Single-column stacking, larger tap targets, hamburger nav, optimized image loading. Mobile-first by default.

Per-breakpoint overrides

Change anything, just for that device

Padding, font size, alignment, visibility, layout — every property has a per-breakpoint override. Adjust mobile spacing without touching desktop.

  • Typography overridesDifferent font sizes per device, line-height adjustments, letter-spacing tweaks.
  • Show / hide blocksHide a complex chart on mobile. Show a simplified version. No media query gymnastics.
  • Layout reflowChange column counts, switch from grid to stack, reorder blocks for mobile.
