What Is Web Development?

Are you curious about how websites and web apps come to life on the internet? Web development refers to the process of building and maintaining websites—from the initial idea to the live, functioning product users interact with every day.

Web development is not just about writing code—it’s a combination of design, coding, functionality, performance, and maintenance, all working together to deliver a seamless user experience.

It’s a combination of several disciplines, including website design, programming, database management, and performance optimization. Whether it’s a simple personal blog or a complex e-commerce platform, what is web development powers it behind the scenes.

There are two main approaches to developing websites:

Coding from Scratch

This method involves building a website’s structure, design, and functionality entirely through programming languages such as:

• HTML (HyperText Markup Language): Defines the structure and content of the web page.

• CSS (Cascading Style Sheets): Controls the visual styling and layout.

• JavaScript: Adds interactivity, animations, and dynamic content.

This approach provides complete control and customization and is ideal for complex websites or businesses with unique functionality requirements.
