Definition of Website
A website (also written as web
site)
A collection of web pages and
related content
Identified by a common domain
name
Published on at least one web
server.
wikipedia.org,
google.com,
amazon.com, and etc…

Introduction to Web
• A document on the web is called a Web Page.
• A Web page is identified by Uniform Resource Locator
(URL).
• A URL is also commonly referred to as a Web Address.
• A website refers to the location on the internet of the Web
pages and related files.

Definition:
Developing a Web site for
the Internet or an intranet.
Range from developing
A simple single static page of
plain text to
complex web applications,
electronic businesses, and
social network services.

Do you imagine how
this page would like
without HTML

No HTML
•Without any markup to give your page content
structure, the browser renders unformatted and
unstyled text.
•HTML Tags give structure and meaning to
your content.

Let us Add HTML tags to our
page…
Looks Better….
But still not Good …

But What should we do to make
the page look nice ?
The answer is
use CSS….

Rules:
Set of rules defining how an html element will be “presented” in the browser.
CSS Rules:
p
{
color: red;
}
#title
{
font-style: italic;
Border: 1px dotted blue;
}
.content {
Font-weight: bold;
Background: yellow;
}

Something can and can’t change with CSS:
Can Change
• colors
• font
• font size
• backgrounds
• spacing
• sizes
• borders
• Position(layout)
Can’t change
• content
• Markup

After adding CSS to page:
Looks Perfect !

Now time for Actions !
Java Script

JavaScript is not a Java:
• JavaScript was not developed at Sun Microsystems, the
home of java.
• JavaScript was developed at Netscape in 1995.
• It’s not a light version of Java.
• It was not based on Java.

JavaScript:
Classic JavaScript is a
client-side language
used to add interactivity to
your web pages.

Some JavaScript Frameworks in
Recent Trend:
• Angular JS
• React JS
• Node JS
• Vue JS

Python:
Now, it's my belief that Python is a lot easier than to teach to students
programming and teach them C or C++ or Java at the same time
because all the details of the languages are so much harder. Other
scripting languages really don't work very well there either.
- Guido van Rossum.

Python
• Python is an interpreted, object-oriented, high-level programming
language with dynamic semantics. Its high-level built in data
structures, combined with dynamic typing and dynamic binding.
• One area where Python shines is web development. Python offers
many frameworks to power some of the world’s most popular sites
such as Spotify, Mozilla, Reddit, the Washington Post and Yelp.

Python Frameworks:
• A framework is a collection of modules or packages which helps in
writing web applications. While working on frameworks in python
we don’t have to worry about the low level details such as protocols,
sockets or thread management.

Operations Involved in
Frameworks:
• Url Routing – Routing is the mechanism of mapping the URL directly
to the code that creates the web page.
• Input form handling and validation – Suppose you have a form which
takes some input, the idea is to validate the data and then save it.
• Output formats with template engine – A template engine allows
the developers to generate desired content types like HTML, XML,
JSON.

Operations Involved in
Frameworks:
• Database connection – Database connection configuration and
persistent data manipulation through an ORM.
• Web security – Frameworks give web security against cross-site
request forgery aka CSRF, sql injection, cross-site scripting and other
common malicious attacks.
• Session storage and retrieval – Data stored in the session storage
gets cleared when the page session ends.

Classification of Frameworks:
• Full (high-level)
- Come with many pre installed components and lot of low level
task automation.
• Micro (low-level)
- Come with many pre installed components and lot of low level
task automation.

Python Frameworks:
• Full (high-level)
• Django
• Web2py
• Turbogears
• Micro (low-level)
• Flask
• Pyramid
• CherryPy
• Bottle.py

MySQL:
• MySQL is the most popular database system used in Web
Development.
• MySQL is a database system used on the web.
• MySQL is a database system that runs on a server.
• MySQL is ideal for both small and large applications.
• MySQL is very fast, reliable, and easy to use.
• The data in a MySQL database are stored in tables. A table is a
collection of related data, and it consists of columns and rows.

Job Options in Web Development:
• Application Developer.
• Web developer.
• UI/UX Developer.
• Web Content Manager.
