Open Source CSS

CSS for the post-build-tool era.

Stride is a modern CSS framework built entirely on oklch color, @property animations, color-mix(), and container queries. No PostCSS. No config. Just link the stylesheet and go.

@property Animations

Animate anything.
Even colors.

Stride uses CSS @property to register custom properties with defined syntax. This unlocks smooth transitions on oklch channels — hue shifts, lightness fades, chroma pulses — that are impossible with standard CSS custom properties.

  • Registered custom property animations
  • Smooth oklch channel transitions
  • Zero JavaScript required

color-mix()

Native color blending.

Every hover state, focus ring, and gradient in Stride uses color-mix(in oklch, ...) for perceptually uniform blending. No preprocessor needed. No color palette explosion. Just clean, mathematical color relationships.

  • Perceptually uniform mixing
  • No preprocessor required
  • Dynamic theme generation
