This document summarizes a lecture on Bootstrap, an open-source front-end framework. It discusses Bootstrap's grid system, components like buttons, images, tables and dropdowns, and how to make sites responsive. Key aspects covered include using containers, rows and columns to layout content, different types of buttons and icons, responsive tables, image styling classes and media queries to control elements based on screen width. The document encourages exploring Bootstrap's documentation to learn about other components like forms, carousels and converting previous assignments to use Bootstrap for layout.

4.  www.getbootstrap.com
 Go to Getting started
 There are two ways
 Online
 You need internet connection
 Offline
 Download the files … can later use them
 Preferred is second one
 Copy the basic template
 Download the html5shiv.js and
respond.js if want offline
 its ready!

5.  Center contents in screen
 Leave some margins right & left
 Work according to device width
 Use class container
<div class=“container”>
<div> … </div>
<p> … </p>
</div>

6.  Horizontal
 Clear one another no matter what happens
 E.g. float is set to elements (created columns inside)
 Use class row
<div class=“container”>
<div class=“row”> … </div>
<div class=“row”> … </div>
</div>
This gray is intentionally
applied using well class
Not a part of row

7.  Divide the row into columns
 There are 12 columns in a row
 Will change position when screen size
changes
 Use class col-X-N
 N can be 1 to 12
 Example
 col-md-6
 col-lg-3
 col-xs-12
 X can be
 xs (extra small device width)
 sm (small device width)
 md (medium device width)
 lg (large device width)

8. <div class=“container”>
<div class=“row”>
<div class=“col-md-6”>First Column 50%</div>
<div class=“col-md-3”>Second Column 25%</div>
<div class=“col-md-3”>Third Column 25%</div>
</div>
</div>
This gray is intentionally
applied using well class
Not a part of col

9.  Device width & break point according to xs, sm, md & lg
 Point at which column occupies next row
 It is different for different type of columns (xs, sm, md, lg)
 Media query comes in handy with device width
 What is the break point for column of type lg?
 What if we do not want a break point?

10. <div class="row">
<div class="col-xs-6 col-md-3"><div class="well">First column</div></div>
<div class="col-xs-6 col-md-3"><div class="well">Second column</div></div>
<div class="col-xs-6 col-md-3"><div class="well">Third column</div></div>
<div class="col-xs-6 col-md-3"><div class="well">Fourth column</div></div>
</div>
md or xs ? Depend on screen

11. <div class="row">
<div class="col-md-4"><div class="well">First column</div></div>
<div class="col-md-4 col-md-offset-4"><div class="well">Second
column</div></div>
</div> col-X-offset-N
Adds margin on right

12.  Hide the things according to device width
 For example: show sidebar if width>md else hide it
 For example: show Slider if width>sm else hide it
<div class="row">
<div class="col-md-3 hidden-lg"><div class="well">First column</div></div>
<div class="col-md-3 hidden-md"><div class="well">Second column</div></div>
<div class="col-md-3"><div class="well">Third column</div></div>
<div class="col-md-3"><div class="well">Fourth column</div></div>
</div>

13. <a href="#" class="btn">Simple Btn</a>
<a href="#" class="btn btn-info">Info Btn</a>
<a href="#" class="btn btn-primary">Primary Btn</a>
<a href="#" class="btn btn-warning">Warning Btn</a>
<a href="#" class="btn btn-success">Success Btn</a>

<a href="#" class="btn btn-info btn-lg">LG Btn</a>
<a href="#" class="btn btn-info btn-sm">SM Btn</a>

16.  If screen width is going smaller than table may be it will overflow
 To avoid this wrap the table in div with class table-responsive
 It will create scrollbar when above situation occur
<div class=“table-responsive”
<table class="table table-hover">
…
</table>
</div>

17.  Outer div wrap action button and list
