What's included

Bootstrap is downloadable in two forms, within which you'll find the following directories and files, logically grouping common resources and providing both compiled and minified variations.

Precompiled Bootstrap

Once downloaded, unzip the compressed folder to see the structure of (the compiled) Bootstrap. You'll see something like this:

{% highlight bash %} bootstrap/ ├── css/ │ ├── bootstrap.css │ ├── bootstrap.css.map │ ├── bootstrap.min.css │ ├── bootstrap.min.css.map │ ├── bootstrap-theme.css │ ├── bootstrap-theme.css.map │ ├── bootstrap-theme.min.css │ └── bootstrap-theme.min.css.map ├── js/ │ ├── bootstrap.js │ └── bootstrap.min.js └── fonts/ ├── icons-halflings-regular.eot ├── icons-halflings-regular.svg ├── icons-halflings-regular.ttf ├── icons-halflings-regular.woff └── icons-halflings-regular.woff2 {% 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. Fonts from Icons are included, as is the optional Bootstrap theme.

Bootstrap source code

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

{% highlight bash %} bootstrap/ ├── less/ ├── js/ ├── fonts/ ├── dist/ │ ├── css/ │ ├── js/ │ └── fonts/ └── docs/ └── examples/ {% endhighlight %}

The less/, js/, and fonts/ are the source code for our CSS, JS, and icon fonts (respectively). 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.
