Specifications
Customize everything with Sass
Bootstrap utilizes Sass for a modular and customizable architecture. Import only the components you need, enable global options like gradients and shadows, and write your own CSS with our variables, maps, functions, and mixins.
Build and extend in real-time with CSS variables
Bootstrap 5 is evolving with each release to better utilize CSS variables for global theme styles, individual components, and even utilities. We provide dozens of variables for colors, font styles, and more at a :root level for use anywhere.
Components, meet the Utility API
New in Bootstrap 5, our utilities are now generated by our Utility API. We built it as a feature-packed Sass map that can be quickly and easily customized.

Reviewed on Sept. 2, 2024Bootstrap is a fantastic front-end framework that makes building responsive, mobile-first websites quick and easy. It offers a wide range of pre-designed components and a flexible grid system, allowing for fast development without sacrificing design quality. However, customization beyond the provided styles can be challenging for beginners.
