Web Development is a combination of the words i.e., Web (refers to web pages, websites, or anything over the internet) and Development (the act of building such applications from scratch). It entails building and maintaining websites and web-based applications such as social networking sites (like Instagram, Facebook, Linkedin, Twitter, etc.), online eCommerce sites (like Flipkart, Amazon, Myntra, etc.), and many more. This process involves creating a website that looks great, runs smoothly, and has a seamless user experience. Web design, web publishing, web programming, and database management are all part of this process.  

These are the tasks that web developers, or 'devs', perform using various coding languages. Web Developers must have a good understanding of different types of web technologies including HTML (Hypertext Markup Language), CSS (Cascading Style Sheets), PHP (Hypertext Preprocessor), BootStrap, Servlets, JavaScript, etc. The programming languages they use will vary depending on the tasks they are performing and the platform they are using. A career in web development is highly sought after worldwide and well paid, making it a great career option.
