Restyle Every Pixel with Custom Themes

Reskin your public forms, assessments, and pages with real CSS. Start from a curated theme library, write your own stylesheet, or describe a look and let AI draft it — all safely sandboxed.

Write real CSS — safely

No theming DSL, no limited color pickers. Themes are genuine stylesheets targeting a stable, documented selector contract, compiled through a strict sanitizer so they can restyle everything and break nothing.

  • Stable styling hooks on every participant-facing surface
  • Design tokens for colors, radius, and typography
  • Full light and dark mode support
  • Every theme is sanitized and scoped before it ships
  • One theme reskins forms, assessments, and pages alike

:root {
--primary: oklch(0.63 0.2 295);
--radius: 1rem;
}
.amp-card {
border-radius: var(--radius);

.amp-btn-submit {
background: var(--primary);

Motion is part of the theme

Themes don't stop at colors. Drive question entrance animations straight from CSS — pick a preset, tune duration and stagger, and stay accessible by default.

  • Five entrance presets: fade-up, scale-in, slide, blur-in, flip
  • Tune duration and per-question stagger with CSS variables
  • Pure CSS configuration — themes never run scripts
  • Respects each visitor's reduced-motion preference
  • Falls back gracefully when no motion is configured
