├── css/
│ ├── bootstrap.css
│ ├── bootstrap.min.css
│ ├── bootstrap-theme.css
│ └── bootstrap-theme.min.css
├── js/
│ ├── bootstrap.js
│ └── bootstrap.min.js
└── fonts/
├── glyphicons-halflings-regular.eot
├── glyphicons-halflings-regular.svg
├── glyphicons-halflings-regular.ttf
└── glyphicons-halflings-regular.woff
It comes with both minified versions as well as without the minification. Minified version can perform better, so they are the preferred files to use.
As you can see the bootstrap files include CSS, JavaScript and font files.
Bootstrap is built to work best in the latest desktop and mobile browsers, meaning older browsers might display differently styled, though fully functional, renderings of certain components.
