Basic Components of Web Development
Web development involves creating websites and web applications. It has three
main components:
1. Front-end Development: This focuses on what users see and interact with
on a website. The following fundamentals are used to design interactive
Front-ends:
• HTML structures the content on web pages, like headings, paragraphs,
images, and links.
• CSS styles the content on web pages, changing colors, fonts, and layout to
enhance the appearance.
• JavaScript adds interactivity to web pages, making them dynamic and
engaging. It allows features such as forms, animations, and games.
2. Back-end Development: This manages the behind-the-scenes functinality
of a website, including servers, databases, and application logic. Key backend
technologies are:
• Web Servers are computers that store and deliver web pages to users
when they enter a URL.
• Databases store and manage data, like user information, product details,
and website content.
• Back-end Programming Languages like PHP, Python, and Ruby handle
tasks such as processing forms, and managing user logins.
Example: Login System
A login system is a common feature in web development, allowing users to
access their accounts on a website. This example will illustrate the roles of
front-end and back-end development, as well as the concept of full-stack
development.
3. Full-Stack Development
In the case of login system, a full-stack developer will create the User Interface
(UI) for front-end and handle user authentication and database interaction for
back-end.
