Precompiled Bootstrap

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

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.

{{< bs-table "table" >}}

CSS files	Layout	Content	Components	Utilities
bootstrap.css bootstrap.min.css bootstrap.rtl.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]({{< docsref "/layout/grid" >}})	—	—	[Only flex utilities]({{< docsref "/utilities/flex" >}})
bootstrap-utilities.css bootstrap-utilities.rtl.css bootstrap-utilities.min.css bootstrap-utilities.rtl.min.css	—	—	—	Included
bootstrap-reboot.css bootstrap-reboot.rtl.css bootstrap-reboot.min.css bootstrap-reboot.rtl.min.css	[Only Reboot]({{< docsref "/content/reboot" >}})	—	—	[Only flex utilities]({{< docsref "/utilities/flex" >}})
{{< /bs-table >}}

JS files

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

{{< bs-table "table" >}}

bootstrap.bundle.js bootstrap.bundle.min.js	Included
bootstrap.js bootstrap.min.js	–
{{< /bs-table >}}

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/
│          └── {{< param docs_version >}}/
│              └── 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.
