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.
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. On components and utilities, CSS variables are scoped to the relevant class and can easily be modified.
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. It's never been easier to add, remove, or modify any utility classes. Make utilities responsive, add pseudo-class variants, and give them custom names.
// Create and extend utilities with the Utility API
Bootstrap Icons is an open source SVG icon library featuring over 1,500 glyphs, with more added every release. They're designed to work in any project, whether you use Bootstrap itself or not. Use them as SVGs or icon fonts—both options give you vector scaling and easy customization via CSS.
Take Bootstrap to the next level with premium themes from the official Bootstrap Themes marketplace. Themes are built on Bootstrap as their own extended frameworks, rich with new components and plugins, documentation, and powerful build tools.
