Web Development is the process of creating, designing, and maintaining websites to ensure functionality, responsiveness, and a seamless user experience. It involves front-end development, which focuses on the visual aspects of a site using technologies like HTML, CSS, and JavaScript, and back-end development, which manages server-side logic, databases, and application functionality. Web development also includes optimizing website performance, ensuring mobile responsiveness, and integrating security features to protect user data. Whether for businesses, e-commerce, or personal projects, effective web development enhances online presence, improves accessibility, and helps organizations reach their target audience efficiently in the digital world.
