Bootstrap 3:

Bootstrap is the most popular HTML, CSS, and JavaScript framework for developing responsive, mobile-first web sites.

What is Bootstrap?

    Bootstrap is a free front-end framework for faster and easier web development
    Bootstrap includes HTML and CSS based design templates for typography, forms, buttons, tables, navigation, modals, image carousels and many other, as well as optional JavaScript plugins
    Bootstrap also gives you the ability to easily create responsive designs



Create First Web Page With Bootstrap

1. Add the HTML5 doctype

Bootstrap uses HTML elements and CSS properties that require the HTML5 doctype.

Always include the HTML5 doctype at the beginning of the page, along with the lang attribute and the correct character set:
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
  </head>
</html>

2. Bootstrap 3 is mobile-first

Bootstrap 3 is designed to be responsive to mobile devices. Mobile-first styles are part of the core framework.

To ensure proper rendering and touch zooming, add the following <meta> tag inside the <head> element:
<meta name="viewport" content="width=device-width, initial-scale=1">

The width=device-width part sets the width of the page to follow the screen-width of the device (which will vary depending on the device).

The initial-scale=1 part sets the initial zoom level when the page is first loaded by the browser.

3. Containers

Bootstrap also requires a containing element to wrap site contents.

There are two container classes to choose from:

    The .container class provides a responsive fixed width container
    The .container-fluid class provides a full width container, spanning the entire width of the viewport

Note: Containers are not nestable (you cannot put a container inside another container).


Bootstrap's Default Settings:
Bootstrap's global default font-size is 14px, with a line-height of 1.428. 
HTML elements styled a little bit different by Bootstrap than browser defaults.
