HTML Introduction
• HTML stands for Hyper Text Markup Language.
• HTML describes the structure of Web pages using
markup.
• HTML elements are represented by tags.
• Browsers do not display the HTML tags, but use them
to render the content of the page.

HTML Editors
• Web pages can be created and modified by using
professional HTML editors.
• We believe using a simple text editor is a good way
to learn HTML.
• There are Many HTML Editors .
like Notepad , Notepad++.

Save and Run HTML Page
• Windows 8 or later:
Open the Start Screen (the window symbol at the
bottom left on your screen). Type Notepad.
• Windows 7 or earlier:
Open Start > Programs > Accessories > Notepad
• Save the file on your computer. Select File > Save as
in the Notepad menu.
• Name the file "index.htm“ or index.html
• Double click on the file and Run.

HTML Elements
• An HTML element usually consists of a start tag and
end tag, with the content inserted in between:
<tagname>Content</tagname>
• The HTML element is everything from the start tag to
the end tag:
<p>My first paragraph.</p>
<b>Hello World</b>

• The <img> tag is empty, it contains attributes only,
and does not have a closing tag.
• The src attribute specifies the URL (web address) of
the image:
<img src="url" alt="some_text">

HTML Images
• The alt attribute provides an alternate text for
an image, if the user for some reason cannot
view it (because of slow connection, an error
in the src attribute, or if the user uses a screen
reader).
• If a browser cannot find an image, it will
display the value of the alt attribute.

HTML Tables
• An HTML table is defined with the <table> tag.

files like:

The HTML <head> Element
• The <head> element is a container for
metadata (data about data) and is placed
between the <html> tag and the <body> tag.

CSS
• CSS stands for Cascading Style Sheets.
• CSS describes how HTML elements are to be
displayed on screen, paper, or in other
media.
• CSS saves a lot of work. It can control the
layout of multiple web pages all at once.

Types of CSS
• CSS can be added to HTML elements in 3 ways:
– Inline - by using the style attribute in HTML elements.
– Internal - by using a <style> element in the <head>
section.
– External - by using an external CSS file.
• The most common way to add CSS, is to keep the
styles in separate CSS files. However, here we will
use inline and internal styling, because this is
easier to demonstrate, and easier for you to try it
yourself.

Inline CSS
Example:
• An inline CSS is used to apply a unique style to
a single HTML element.
• An inline CSS uses the style attribute of an
HTML element.
<h1 style="color:blue;">This is a Blue
Heading</h1>

Internal CSS
• An internal CSS is used to define a style for a
single HTML page.
• An internal CSS is defined in the <head>
section of an HTML page, within a <style>
element:

External CSS
• An external style sheet is used to define the
style for many HTML pages.
• With an external style sheet, you can change
the look of an entire web site, by changing
one file!
• To use an external style sheet, add a link to it
in the <head> section of the HTML page:

JavaScript
• JavaScript is the programming language of HTML
and the Web.
• JavaScript is easy to learn.
• JavaScript is Case Sensitive
Why Study JavaScript?
• JavaScript is one of the 3 languages all web
developers must learn:
1. HTML to define the content of web pages
2. CSS to specify the layout of web pages
3. JavaScript to program the behavior of web pages

JavaScript
 The <script> Tag
• In HTML, JavaScript code must be inserted
between <script> and </script> tag
<script>
document.getElementById("demo").innerHT
ML = "My First JavaScript";
</script>

JavaScript
 JavaScript Can Change HTML Content
• One of many JavaScript HTML methods is
getElementById().
• This example uses the method to "find" an
HTML element (with id="demo") and changes
the element content (innerHTML) to "Hello
JavaScript":

JavaScript
 JavaScript Variables
• In a programming language, variables are
used to store data values.
• JavaScript uses the var keyword to declare
variables.
Example:
var x;
x = 6;

JSON
 JSON - Introduction
• JSON: JavaScript Object Notation.
• JSON is a syntax for storing and exchanging
data.
• JSON is text.

JSON
 JSON Data - A Name and a Value
• JSON data is written as name/value pairs.
• A name/value pair consists of a field name (in
double quotes), followed by a colon, followed
by a value:

JSON
 Data Types
 JSON Strings
– Strings in JSON must be written in double quotes.
Example:
{ "name":"John" }

JSON
 Data Types
 JSON Numbers
– Numbers in JSON must be an integer or a floating
point.
Example:
{ "age":30 }

JSON Objects
Syntax:
Example
{ "name":"John", "age":30, "car":null }

JSON
 Accessing Object Values
• We can access the object values by using dot
(.) notation.
Example:
myObj = { "name":"John", "age":30, "car":null };
x = myObj.name;

JSON
 Arrays
Example:
[ "Ford", "BMW", "Fiat" ]
 Accessing Array Values
• You access the array values by using the index number:
Example:
x = myObj.cars[0];

JSON For Loop
Syntax:
var x;
var z="";
x={"username":["two","three"],"password":"admin@123"};
for(i=0;i<x.username.length;i++)
{
z+=x.username[i]+"<br>";
}
document.getElementById("demo").innerHTML=z;

JSON
 JSON.parse()
Syntax:
JSON.parse('{ "name":"John", "age":30,"city":"New
York"}');

AngularJS
• AngularJS extends HTML with new attributes.
• AngularJS is perfect for Single Page Applications (SPAs).
• AngularJS is easy to learn.
• AngularJS is a JavaScript framework. It is a library
written in JavaScript.
• AngularJS is distributed as a JavaScript file, and can be
added to a web page with a script tag:
<script
src="https://ajax.googleapis.com/ajax/libs/angularjs/1.
6.4/angular.min.js"></script>

AngularJS
• AngularJS starts automatically when the web page has
loaded.
• The ng-app directive defines an AngularJS application.
• The ng-model directive binds the value of HTML
controls (input, select, textarea) to application data.
<div ng-app="">
<p>My first expression: {{ 5 + 5 }}</p>
</div>
</body>
</html>

AngularJS
 ng-model
Example:
<div ng-app="">
<input type="text" ng-model="user">
{{user}}
</div>

AngularJS
 ng-init
Syntax:
<div ng-app="">
<input type="text"
ng-init="user=‘admin'; pass='admin@123'">
{{user}}
</div>

AngularJS
 AngularJS Objects
<div ng-app="" ng-init="person={firstName:'John',lastName:'Doe'}">
<p>The name is {{ person.lastName }}</p>
</div>
 AngularJS Arrays
<div ng-app="" ng-init="points=[1,15,19,2,40]">
<p>The third result is {{ points[2] }}</p>
</div>

AngularJS
 ng-repeat
<div ng-app="" ng-init="names=[
{name:'Jani',country:'Norway'},
{name:'Hege',country:'Sweden'},
{name:'Kai',country:'Denmark'}]">
<p>Looping with objects:</p>
<ul>
<li ng-repeat="x in names">
{{ x.name + ', ' + x.country }}</li>
</ul>
</div>
