Components

Logically grouping of contents and common assets.

Heads up! 'bootstrap.less' has been renamed to 'default.less', which compiles to 'default.css'.

Please note that all JavaScript plugins require jQuery to be included.

Bootstrap comes equipped with HTML, CSS, and JS for all sorts of things, but they can be summarized with a handful of categories visible at the top of the Bootstrap documentation.

Docs sections

Scaffolding

Global styles for the body to reset type and background, link styles, grid system, and two simple layouts.

Base CSS

Styles for common HTML elements like typography, code, tables, forms, and buttons. Also includes Glyphicons, a great little icon set.

Basic styles for common interface components like tabs and pills, navbar, alerts, page headers, and more.

Javascript plugins

Similar to Components, these Javascript plugins are interactive components for things like tooltips, popovers, modals, and more.

List of components

Together, the Components and Javascript plugins sections provide the following interface elements:

Button groups
Button dropdowns
Navigational tabs, pills, and lists
Navbar
Labels
Badges
Page headers and hero unit
Thumbnails
Alerts
Progress bars
Modals
Dropdowns
Tooltips
Popovers
Accordion
Carousel
Typeahead

In future guides, we may walk through these components individually in more detail. Until then, look for each of these in the documentation for information on how to utilize and customize them.

With a brief intro into the contents out of the way, we can focus putting Bootstrap to use. To do that, we'll utilize a basic HTML template that includes everything we mentioned in the File structure.

Now, here's a look at a typical HTML file:

<!DOCTYPE html>
<html>
  <head>
    <title>Bootstrap 101 Template</title>
  </head>
  <body>
    <h1>Hello, world!</h1>
    <script src="http://code.jquery.com/jquery-latest.js"></script>
  </body>
</html>

To make this a Bootstrapped template, just include the appropriate CSS and JS files:

<!DOCTYPE html>
<html>
  <head>
    <title>Bootstrap 101 Template</title>
    <!-- Bootstrap -->
    <link href="css/bootstrap.min.css" rel="stylesheet">
  </head>
  <body>
    <h1>Hello, world!</h1>
    <script src="http://code.jquery.com/jquery-latest.js"></script>
    <script src="js/bootstrap.min.js"></script>
  </body>
</html>

And you're set! With those two files added, you can begin to develop any site or application with Bootstrap.

Move beyond the base template with a few example layouts. We encourage folks to iterate on these examples and not simply use them as an end result.

Basic marketing site

Featuring a hero unit for a primary message and three supporting elements.
Fluid layout

Uses our new responsive, fluid grid system to create a seamless liquid layout.
Starter template

A barebones HTML document with all the Bootstrap CSS and javascript included.
