Within the download you’ll find the following directories and files, logically grouping common assets and providing both compiled and minified variations. You’ll see something like this:
bootstrap/ ├── css/ │ ├── bootstrap.css │ ├── bootstrap.css.map │ ├── bootstrap.min.css │ ├── bootstrap.min.css.map │ ├── bootstrap-grid.css │ ├── bootstrap-grid.css.map │ ├── bootstrap-grid.min.css │ ├── bootstrap-grid.min.css.map │ ├── bootstrap-reboot.css │ ├── bootstrap-reboot.css.map │ ├── bootstrap-reboot.min.css │ └── bootstrap-reboot.min.css.map └── js/ ├── bootstrap.bundle.js ├── bootstrap.bundle.min.js ├── bootstrap.js └── bootstrap.min.js
We provide compiled CSS and JS (
bootstrap.*), as well as compiled and minified CSS and JS (
bootstrap.min.*). CSS 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, but not jQuery.
