bootstrapt

Bootstrapt is an open-source front-end toolkit for building responsive web interfaces. It provides a compact collection of CSS and JavaScript components designed to speed UI development while remaining lightweight and accessible.

The project positions itself as an alternative to larger frameworks, prioritizing a minimal footprint, a clear naming scheme, and predictable behavior across modern browsers. It is maintained by an open-source community and is distributed via npm and optionally via a CDN.

Key features include a responsive grid system, a set of common UI components (buttons, forms, cards, navs, modals), and utilities for spacing and typography. Bootstrapt uses CSS custom properties for theming, enabling developers to adjust colors, breakpoints, and sizes without editing core styles. The architecture favors modular CSS and optional JavaScript plugins that progressively enhance pages.

Usage and development workflow involve including the framework via CDN or installing through npm, then applying class names to markup. Developers can customize with a Sass-based build or use prebuilt themes. The framework adopts a mobile-first approach and emphasizes accessibility best practices. The ecosystem includes a small gallery of third-party themes and extensions, and a command-line tool for builds and optimization.

Reception and status: Bootstrapt has niche adoption among small teams and educators seeking a lean alternative to heavier frameworks. It is commonly used for rapid prototyping and educational projects. It competes with Bootstrap, Bulma, and Foundation but emphasizes simplicity, clarity, and ease of use.
