marx-css@5.0.0

Major Changes

• 052ce74: Marx 5: a ground-up modernization for the 2026 web, borrowing patterns from Tailwind CSS Preflight v4.3 and shadcn/ui typeset.

  Highlights

  • Automatic light/dark mode via color-scheme + light-dark() — force a scheme with :root { color-scheme: light } (or dark).
  • Zero specificity: every rule is wrapped in :where() inside cascade layers (marx.base, marx.content, marx.forms), so any consumer CSS overrides Marx.
  • New --marx-* design-token API (oklch colors, rem type scale) replaces the old unprefixed variables — see the migration table in the README.
  • Modern preflight-style base replaces the vendored sanitize.css snapshot.
  • Typeset-style rhythm: one-directional margin-block-start flow, logical properties throughout (RTL-ready), text-wrap: balance/pretty, styled dialog/[popover]/kbd, accent-colored native controls, field-sizing textareas.
  • Accessibility: :focus-visible outlines everywhere (no more removed outlines), :user-invalid instead of :invalid, transitions gated behind prefers-reduced-motion, print styles, WCAG AA-checked palette in both schemes.
  • Build swapped from PostCSS to Lightning CSS; package gains exports/style/sideEffects fields.

  Breaking changes

  • Theming variables renamed (--md-pad → --marx-space-md, --link-color → --marx-link, …) — full table in the README.
  • Pages now follow the OS dark-mode preference by default; add :root { color-scheme: light } to keep v4's always-light look.
  • Links are subtly underlined; type scale is rem-based; browser floor is Baseline 2024 (Chrome/Edge 123+, Firefox 120+, Safari 17.5+), with older browsers degrading to a readable light theme.
