Precompiled Bootstrap

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

{% highlight plaintext %} 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 {% endhighlight %}

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.*). 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.

CSS files

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

CSS files	Layout	Content	Components	Utilities
bootstrap.css bootstrap.min.css	Included	Included	Included	Included
bootstrap-grid.css bootstrap-grid.min.css	Only grid system	Not included	Not included	Only flex utilities
bootstrap-reboot.css bootstrap-reboot.min.css	Not included	Only Reboot	Not included	Not included

JS files

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

JS files	Popper	jQuery
bootstrap.bundle.js bootstrap.bundle.min.js	Included	Not included
bootstrap.js bootstrap.min.js	Not included	Not 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:

{% highlight plaintext %} bootstrap/ ├── dist/ │ ├── css/ │ └── js/ ├── docs/ │ └── examples/ ├── js/ └── scss/ {% endhighlight %}

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 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.
