How to Use Bootstrap?
Bootstrap can be downloaded and the library files can be added to your project. Then those dependent files can be included on the web pages. Another way to use Bootstrap is, instead of downloading bootstrap the dependent files can be directly linked to Bootstrap CDN. This Bootstrap CDN is provided by MaxCDN. Advantage of using a CDN hosted file is that, when a user requests the page, these files will be served from a server that is closest to the requesting user location. Add the following to the HTML Head tag in the web page where you want to use Bootstrap.
<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
<!-- Optional theme -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap-theme.min.css">
Basic Bootstrap Page
Following is an example of a basic bootstrap page. Points to note are,
- Include the HTML5 doctype, lang and charset
- Declare viewport meta tag for page responsiveness
- Choose between fixed or fluid width container. As the name suggests, fluid width uses the complete width of the device viewport.
<!DOCTYPE html> <html lang="en">
<title>Bootstrap Example Page</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
<body> <div class="container"> <h1>Bootstrap Example Page</h1> <p>A paragraph of text</p> </div> </body>
