What is Frontend and Backend? (Part 1) When learning web development, one of the first concepts you need to understand is the difference between the frontend and the backend. Every website or web application you use, whether it's Facebook, YouTube, an online banking system, or an e-commerce platform, is built using these two main parts. Before defining them, let's understand what happens whenever you interact with a website. Every time you open a webpage, click a button, submit a form, search for a product, or log in to your account, your browser sends an HTTP request to a server. An HTTP request is a message sent from your browser (the client) to a server asking for a resource or requesting the server to perform a specific action. The server receives the request, processes it, and sends back an HTTP response containing the requested webpage, data, or the result of the action. Your browser then displays the response so that you can see and interact with it. This communication happens continuously while you use a website. What is Frontend? The frontend is the part of a website or application that users can see and interact with. It is also called the client-side because it runs in the user's web browser or mobile application. Everything visible on your screen belongs to the frontend, including: • Navigation menus • Buttons • Images • Forms • Text • Colors • Layouts • Animations For example, when you visit an online shopping website, the products you see, the search bar, the shopping cart icon, and the checkout page are all part of the frontend. The frontend is responsible for providing a good user experience by making websites visually appealing, responsive, and interactive. The three core technologies used to build the frontend are: HTML – Creates the structure of the webpage. CSS – Styles the webpage and controls its appearance. JavaScript – Adds interactivity and dynamic behavior. Although the frontend is what users interact with directly, it cannot work alone. Whenever users request data or perform an action, the frontend communicates with another part of the application called the backend. In Part 2, we will explore what the backend is, how it processes requests, interacts with databases, and works together with the frontend to build complete web applications.
