Why use it
Semantic by default. Any stack.
npm or CDN. Class-based or classless. Dark is a build, not a theme script.
- Semantic HTML
Style real elements. Pages without a class on every heading and form.
- Classless build
Point at bullframe-classless.css for plain HTML. No .bf-* classes in that build.
- Dark without JS
Always-dark builds, or system-default builds wired to prefers-color-scheme.
When to use
Use Bullframe for pages, not apps.
Good for docs, blogs, landings, help centers, and forms. If you need a dashboard shell, data grid, or design-system components, use a UI kit instead.
- Good fit
Docs, blogs, landings, help centers, and forms.
- One CSS file
Reset, type, forms, layout. npm or CDN.
- Two markup modes
