    Discover what’s included in Bootstrap, including our precompiled and source code flavors. Remember, Bootstrap’s JavaScript plugins require jQuery.

    Precompiled Bootstrap

    Once downloaded, unzip the compressed folder and you’ll see something like this:

    1. bootstrap/
    2. ├── css/
    3. │   ├── bootstrap-grid.css
    4. │   ├── bootstrap-grid.css.map
    5. │   ├── bootstrap-grid.min.css
    6. │   ├── bootstrap-grid.min.css.map
    7. │   ├── bootstrap-reboot.css
    8. │   ├── bootstrap-reboot.css.map
    9. │   ├── bootstrap-reboot.min.css
    10. │   ├── bootstrap-reboot.min.css.map
    11. │   ├── bootstrap.css
    12. │   ├── bootstrap.css.map
    13. │   ├── bootstrap.min.css
    14. │   └── bootstrap.min.css.map
    15. └── js/
    16.     ├── bootstrap.bundle.js
    17.     ├── bootstrap.bundle.js.map
    18.     ├── bootstrap.bundle.min.js
    19.     ├── bootstrap.bundle.min.js.map
    20.     ├── bootstrap.js
    21.     ├── bootstrap.js.map
    22.     ├── bootstrap.min.js
    23.     └── bootstrap.min.js.map

    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, but not jQuery.

    CSS files

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

    JS files

    Similarly, we have options for including some or all of our compiled JavaScript.

    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:

    1. bootstrap/
    2. ├── dist/
    3. │   ├── css/
    4. │   └── js/
    5. ├── site/
    6. │   └──docs/
    7. │      └── 4.4/
    8. │          └── examples/
    9. ├── js/
    10. └── 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.
