how to use bootstrap in html

Bootstrap CDN

The folks over at MaxCDN graciously provide CDN support for Bootstrap's CSS and JavaScript. Just use these Bootstrap CDN links.

<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css">

<!-- Optional theme -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap-theme.min.css">

<!-- Latest compiled and minified JavaScript -->
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/js/bootstrap.min.js"></script>

 

Install with Bower

Install and manage Bootstrap's Less, CSS, JavaScript, and fonts using Bower.

 $ bower install bootstrap

 

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.

jQuery required

Please note that all JavaScript plugins require jQuery to be included, as shown in the starter template. Consult our bower.json to see which versions of jQuery are supported.
 

Precompiled Bootstrap

Once downloaded, unzip the compressed folder to see the structure of (the compiled) Bootstrap. You'll see something like this:
bootstrap/
├── 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
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.*). Fonts from Glyphicons 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:
bootstrap/
├── less/
├── js/
├── fonts/
├── dist/
│   ├── css/
│   ├── js/
│   └── fonts/
└── docs/
    └── examples/
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.

Compiling CSS and JavaScript

Bootstrap uses Grunt for its build system, with convenient methods for working with the framework. It's how we compile our code, run tests, and more.

Installing Grunt

To install Grunt, you must first download and install node.js (which includes npm). npm stands for node packaged modules and is a way to manage development dependencies through node.js.
Then, from the command line:

1. Install grunt-cli globally with npm install -g grunt-cli.
2. Navigate to the root /bootstrap/ directory, then run npm install. npm will look at the package.json file and automatically install the necessary local dependencies listed there.

When completed, you'll be able to run the various Grunt commands provided from the command line.

Available Grunt commands

grunt dist (Just compile CSS and JavaScript)

Regenerates the /dist/ directory with compiled and minified CSS and JavaScript files. As a Bootstrap user, this is normally the command you want.

grunt watch (Watch)

Watches the Less source files and automatically recompiles them to CSS whenever you save a change.

grunt test (Run tests)

Runs JSHint and runs the QUnit tests headlessly in PhantomJS.

grunt docs (Build & test the docs assets)

Builds and tests CSS, JavaScript, and other assets which are used when running the documentation locally via jekyll serve.

grunt (Build absolutely everything and run tests)

Compiles and minifies CSS and JavaScript, builds the documentation website, runs the HTML5 validator against the docs, regenerates the Customizer assets, and more. Requires Jekyll. Usually only necessary if you're hacking on Bootstrap itself.

Troubleshooting

Should you encounter problems with installing dependencies or running Grunt commands, first delete the /node_modules/ directory generated by npm. Then, rerun npm install.

Basic template

Start with this basic HTML template, or modify these examples. We hope you'll customize our templates and examples, adapting them to suit your needs.

Copy the HTML below to begin working with a minimal Bootstrap document.
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title>Bootstrap 101 Template</title>

    <!-- Bootstrap -->
    <link href="css/bootstrap.min.css" rel="stylesheet">
