HTML CSS JavaScript
HTML, CSS, and JavaScript are the foundational technologies for building web pages and web applications. HTML provides the structure and content, CSS handles the styling and layout, and JavaScript enables interactivity and dynamic behavior. Together, they form the core of front-end web development, allowing developers to create responsive, user-friendly interfaces.
Developers should learn HTML, CSS, and JavaScript as they are essential for any web development role, from building simple static websites to complex single-page applications. Mastery of these technologies is crucial for creating accessible, performant, and engaging user experiences across browsers and devices, and they serve as prerequisites for learning modern frameworks and libraries like React or Vue.js.
