Show Bootstrap Image Using ASP.NET MVC

Introduction

Bootstrap is a free, open-source UI framework developed by Twitter to create responsive Web Applications.

It includes HTML and CSS based design templates along with the optional JavaScript extensions.

Bootstrap can be used with any server side technology and any platform. You can use it with any web application built with any server side technology like ASP.NET, JAVA, PHP etc.

Description

It helps us to create responsive Web Applications faster and easier. A responsive Web Application automatically adapts to the different screen sizes (i.e. desktop computers, laptops, tablets, mobile phones etc.) i.e easy reading and navigation with a minimum of resizing, panning and scrolling across a wide range of devices. It is a multiplatform support interface.

As Bootstrap is the most popular framework, it has a very large community base and excellent documentation.

Steps

To get started with Bootstrap, the first step is to download Bootstrap from http://getbootstrap.com.
This Website also has all the documentation, which you need to get started with Bootstrap.

Unzip the ZIP folder and you should see the folder structure given below. Notice there are 3 sub-folders (css, fonts & js).

Let us understand the use of each file, folder by folder.

CSS part description

bootstrap.css
This is the core CSS for BootStrap, which defines all the style for the various controls and the components.

bootstrap.css.map
When debugging the minified code, the line numbers do not refer to the orignal files. The file that has the .map extension, which is also called as source map file fixes this problem by allowing the Web debuggers to refer to the original context from where the code was generated. This file is useful during the development.

bootstrap.min.css
This is the compressed version, which means all the whitespaces, line breaks and any other extra characters, which have been removed. As a result, the size of the minified file is smaller than the non-minified file. Minified version is usually used on a production Server for an efficient download, whereas the non minified version is used in the development environment, as it is more readable and easy to debug, if there are issues.

bootstrap.min.css.map
Source map file for bootstrap.min.css

bootstrap-theme.css
As the name suggests, this is the theme for bootstrap. Adding the core bootstrap.css is enough for Bootstrap to work. The theme file is optional and is usually used for a visually enhanced experience. For example, if you want 3D effects, gradients, shadows etc.

bootstrap-theme.css.map
Source map file for bootstrap-theme.css

bootstrap-theme.min.css
Minified version of bootstrap-theme.css

bootstrap-theme.min.css.map
Source map file for bootstrap-theme.min.css

Font part description

There are 5 different font files from Glyphicons. These 5 different files are just different formats of the Glyphicon font to support different Browsers.

JS part description

These JavaScript files are optional.

These are required, if you want to use Bootstrap widgets like picture carousel, dropdown menus, collapsible accordian etc. One important thing to keep in mind is that Boostrap JavaScript has a dependency on jQuery, so a reference to jQuery must also exist on the page, where you want to use Bootstrap.

bootstrap.js
This is the non-minified readable version, which is usually used during the development.

bootstrap.min.js
Minified version of bootstrap.js is optimized for the faster download. This is the version, which is usually used in a production environment.

npm.js
npm is a file from Node.js and is used for npm installing Bootstrap. If you are new to Node.js, don't worry, as this is not going to come in the way to understand Bootstrap.

Note

The viewport meta tag ensures proper rendering and touch zooming on a mobile device.
