  2. It helps in building responsive web pages easily. Webpages using Bootstrap will auto adjust to various viewports, like smart phones, tablets and desktop screens.

Quick Start

Configuring Bootstrap

  1. Download the minified Bootstrap package from here. Unzip the package and copy all the 3 folders into your application root or to the folder where you maintain the styles and scripts. Unzipped package,

If you are using Visual Studio, then creating a new web project will automatically include all necessary bootstrap files for start using bootstrap. If it is not included, you can download using Nuget. On solution explorer, right click project and select “Nuget Package Manager..". Search for Bootstrap and click Install. This will download and install the bootstrap into your project.

Alternatively, you can use CDN instead of maintaining a local bootstrap file copies.

  1. Include the bootstrap stylesheet under head section of the webpage(or your master page layout)

 

<head>

<meta charset="utf-8" />

<title>@ViewBag.Title - My ASP.NET MVC Application</title>

<meta name="viewport" content="width=device-width" />

<link href="~/Content/bootstrap.min.css" rel="stylesheet">

</head>

 

The 2 meta tags, that sets charset and viewport are mandatory.

Note- I have copied bootstrap styles to Content folder under root directory.

  1. Include the script file before the <body> closing tag. jQuery is necessary if you will use any bootstrap plugin.

 

<script src="~/Scripts/jquery-1.9.1.min.js"></script>

<script src="~/Scripts/bootstrap.min.js"></script>

</body>

 

Note- - I have copied bootstrap scripts to Scripts folder under root directory.

  1. That’s it. You can now start using bootstrap styles in your project.

 

Applying Bootstrap Styles

Bootstrap provides a responsive fluid design for front end by using a 12 columns Grid Layout system.

Grid Layout

The Grid Layout design splits page into 12 columns (or parts) to form a row and controls can be placed inside each column.

Row with 12 separate columns

 

<div class="row">

  <div class="col-md-1">.col-md-1</div>

  <div class="col-md-1">.col-md-1</div>

  <div class="col-md-1">.col-md-1</div>

  <div class="col-md-1">.col-md-1</div>

  <div class="col-md-1">.col-md-1</div>

  <div class="col-md-1">.col-md-1</div>

  <div class="col-md-1">.col-md-1</div>

  <div class="col-md-1">.col-md-1</div>

  <div class="col-md-1">.col-md-1</div>

  <div class="col-md-1">.col-md-1</div>

  <div class="col-md-1">.col-md-1</div>

  <div class="col-md-1">.col-md-1</div>

</div>

 

A row can also be defined by combining columns. For example, the below row splits a row into 2, first part taking the width of 8 columns and the other taking width of 4 columns.

 

<div class="row">

  <div class="col-md-8">.col-md-8</div>

  <div class="col-md-4">.col-md-4</div>

</div>
