What is Front-End Development?

Front-end development is the process of creating visual elements and interactive components for a website or web application that users can see and interact with. It encompasses everything from designing the layout and structure of web pages using HTML (Hypertext Markup Language) and CSS (Cascading Style Sheets) to implementing dynamic features and user interactions using JavaScript.

Front-end developers are responsible for translating design mockups and wireframes into functional and visually appealing interfaces. They ensure that websites and applications are responsive, user-friendly, and accessible from a variety of devices and browsers. They also work closely with back-end developers to integrate the front-end with server-side logic and data.
