This is the most basic form of Bootstrap: precompiled files for quick drop-in usage in nearly any web project. We provide compiled CSS and JS (bootstrap.*), as well as compiled and minified CSS and JS (bootstrap.min.*). Source maps (bootstrap.*.map) are available for use with certain browsers' developer tools. Bundled JS files (bootstrap.bundle.js and minified bootstrap.bundle.min.js) include Popper.

CSS files

Bootstrap includes a handful of options for including some or all of our compiled CSS.

bootstrap.css bootstrap.rtl.css bootstrap.min.css bootstrap.rtl.min.css	Included	Included	Included	Included
bootstrap-grid.css bootstrap-grid.rtl.css bootstrap-grid.min.css bootstrap-grid.rtl.min.css	Only grid system	—	—	Only flex utilities
bootstrap-utilities.css bootstrap-utilities.rtl.css bootstrap-utilities.min.css bootstrap-utilities.rtl.min.css	—	—	—	Included

Bootstrap source code

The Bootstrap source code download includes the precompiled CSS and JavaScript assets, along with source Sass, JavaScript, and documentation. More specifically, it includes the following and more:

bootstrap/
├── dist/
│   ├── css/
│   └── js/
├── site/
│   └──content/
│      └── docs/
│          └── 5.1/
│              └── examples/
├── js/
└── scss/

The scss/ and js/ are the source code for our CSS and JavaScript. The dist/ folder includes everything listed in the precompiled download section above. The site/docs/ folder includes the source code for our documentation, and examples/ of Bootstrap usage. Beyond that, any other included file provides support for packages, license information, and development.
