Twitter Bootstrap Features
Twitter Bootstrap is a mobile first framework, it means your websites will be fully responsive and will work on desktop, tablets and smart phones. You can make images responsive by adding
.img-responsive class in bootstrap 3. For improved cross-browser rendering, Bootstrap uses Normalize.css, a project by Nicolas Gallagher and Jonathan Neal.
Responsive Grid System Twitter Bootstrap
Twitter Bootstrap has a 12 column responsive, mobile first grid system, which uses predefined classes like
.container to create a primary wrapper for your web page,
.row .col-xs-4, .col-md-1, col-md-4 and others to create grid layouts quickly and easily.
You can use
.col-xs-* to target small screen devices such as mobile phones,
.col-md-* will target medium devices like tablets, desktop and
.col-lg-* will target large screens. * will be replaced with your desired number for grid layout.
For example you can create 2 column layout easily with
.col-md-8 for main area and
.col-md-4 class for sidebar.
Twitter Bootstrap Classes are available for Mobile, tablets and desktops. With Twitter Bootstrap’s these classes you can easily create multi column layouts.
Advance users can use LESS mixins to create more semantic layouts.
For example to create a 2 column layout you can use following code.
<div class="container"> <main class="row"> <article class="col-md-8"> primary content </article> <!--end .col-md-8--> <aside class="col-md-4"> sidebar content </aside><!--end .col-md-4--> </main> <!--end .row--> </div> <!--end .container-->
Typography in Twitter Bootstrap

.danger to color table rows or individual cells.
Making Tables Responsive
Creating responsive tables is simple by wrapping any
.table-responsive to make them scroll horizontally up to small devices (under 768px).
Forms in Twitter Bootstrap
Creating different type of form with bootstrap is also simple and easy. Since version 3 of Twitter Bootstrap inputs, selects, and text areas are 100% wide by default in Bootstrap framework.
You can use predefined grid classes to align labels and groups of form controls in a horizontal layout. Form states will allow you to provide feedback to users.
Buttons and images

Image replacement is simple just apply
.text-hide class to replace an element’s text content with a background image for example for site logo.
Faster mobile-friendly development with Responsive utilities
One of the cool feature of bootstrap 2 was the ability to mark the content so that it only appears in certain devices. That remains in the new version but class names has been changed in version 3.
Bootstrap 3 offers 8 different classes to show or hide content from screen. For example if you apply
.visible-xs to an element, it will only be visible on extra small devices Phones (<768px) and hidden on tablets and desktops.
print classes are also available for toggling content for print. You can use
.visible-print to show and
.hidden-print class to hide content while printing content.
Pre built Components
Pre built components are one of the most cool feature of Bootstrap. Many components are available to make your work flow faster, which includes drop downs, button groups, navigation menus, breadcrumbs, pagination, labels, thumbnails, alerts and many others.
Lets have a look at some of them in details.
Since version 3 bootstrap included 200 glyphs in font format. It is a welcome change because they can be resized and will display perfectly even if the resolution of the screen increases.
It also gives you the ability to color icons, before version 3 of twitter bootstrap you can only use white or black version of icons.
Dropdown and Navigation Menus
.nav-justified. You can use
.nav-justified make tabs or pills equal widths of their parent at screens wider than 768px .
Jumbotron and Thumbnails
Jumbotron is a big area usually spanning the width of web page. Jumbotron is great to draw user attention. It is main component for calling extra attention and to show featured content or information.

Carousal is one of the most popular feature of bootstrap. It can be used to create slide show of featured products or images.

Unofficially, Bootstrap should look and behave well enough in Chromium and Chrome for Linux, Firefox for Linux, and Internet Explorer 7, though they are not officially supported.

Internet Explorer 8 and 9 are also supported, however, some CSS3 properties and HTML5 elements are not fully supported in Internet Explorer 8 and 9 .
Internet Explorer 8 does not support border-radius, box-shadow, transform, transition and placeholder.
