New CSS3 Selectors
 New CSS3 Structural Pseudo-Class Selectors

li:first-of-type { color: red; }
• E:last-of-type - Selects the last element of type E for its parent
li:last-of-type { color: yellow; }
• E:only-child - Selects if E is only the child of its parent
li:only-child { color: blue; }
• E:nth-child(n) - Selects nth child of the element E
li:nth-child(3) { color: yellow; }
• E:nth-last-child(n) - Selects nth last child of the element E
li:nth-last-child(2) { color: red; }

CSS3 – 2D Transforms
 Transformation
• Change of position, shape and size of an element
 CSS3 Transforms
• 2-D: Two Dimensions
• 3-D: Three Dimensions (not covered in this course)
 Transform Operations
• move, scale, spin, stretch and turn elements

CSS3 – 2D Transforms (Contd./-)
 Specified with transform attribute
• Translation – Movement along X-axis and Y-axis
transform: translate( 50px, 100px );
• Rotation – in clock-wise direction
transform: rotate( 5deg );
• Scaling – increase/decrease size along width and height
transform: scale( 2, 2 );
• Skewing – tilting (turning) in X-axis and Y-axis directions
transform: skew( 10deg, 5deg);

CSS3 Transitions
 Changing from one style to another (on an event)
 CSS property on which the transition effect has to take place
 Time Duration over which transition has to take place (smoothly)
 Specified in seconds (s) or milliseconds (ms)

HTML DOM Methods
 DOM Methods – Finding HTML Elements
• getElementById() Method
 Gets the HTML Element with specified ID
• getElementsByClassName() Method
 Gets the HTML Elements with specified class name
document.getElementsByClassName("middlePara")[0].innerHTML = "Welcome
to Edureka!";
document.getElementsByClassName("middlePara")[1].innerHTML = "This is
HTML5, CSS3 and JavaScript Course!";
• getElementsByTagName() method
 Gets the HTML Elements with specified element tag
document.getElementsByTagName("p")[0].innerHTML = "Welcome to
Edureka!";
document.getElementsByTagName("p")[1].innerHTML = "This is HTML5,
CSS3 and JavaScript Course!";

jQuery - Introduction
 jQuery Core – a Cross-Platform JavaScript Library

 Latest Versions
• Version 1.11.3 - has support for IE 6/7/8
• Version 2.1.4 - has NO support for IE 6/7/8
• Development Version
 For use during development of the website
• Minified Version
 For use in production (live / online) use of website

jQuery - Introduction
 Why use jQuery?
• JavaScript Framework
• Separates HTML and JavaScript in a web page
• Eliminates cross-browser incompatibilities
• Simple/Short, Clean and Easy to read, write and understand

jQuery Basics
 Download the latest version
• From jquery.com website
 Reference it in HTML file
• Host it on your Web Server and Use it with <script> tag
<script src="jquery-2.1.3.js"></script>
• Point to a Public Web Server and Use it with <script> tag
 Google CDN Server (recommended) CDN – Content Delivery Network
<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js">
</script>
 Microsoft CDN Server
<script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.11.2.min.js">
</script>
 MaxCDN CDN Server (moved from MediaTemple, before that Amazon)
<script src="http://code.jquery.com/jquery-2.1.3.min.js"></script>
• Do not put the jQuery code in the <script> tag that loads jQuery library

AngularJS - Introduction
 Developed by Google
 Based on MVC Pattern – on Front-End (Browser) side
• Model – Sourcing and Managing Data
• Controller – Application Logic – Decides what/when to display
• View – Presentation of Data – How (Where) to display the data
 In AngularJS
• Model
 Represents current state of the application
 Stored in Object Properties
• View
 Displays the data in the Page’s DOM
• Controller
 Manages the relationship between the Model and the View (JavaScript Code)
• Data Binding Concept
 Map parts of UI to a JavaScript Object’s properties
 Sync between them happens automatically

Advanced Web Programming Topics
 HTML Canvas, WebGL, SVG
 HTML5 Geolocation API
 HTML5 Drag and Drop API
 HTML5 Web Storage API
