Front-end Development: HTML (Hypertext Markup Language): Used for structuring the content of a webpage.
CSS (Cascading Style Sheets): Responsible for styling and layout, determining the presentation of the HTML elements.
JavaScript: Adds interactivity and dynamic behavior to web pages. It is commonly used for client-side scripting.

Web development is a broad field, and developers often specialize in either front-end or back-end development, or both (full-stack development). Staying updated with the latest technologies and best practices is crucial in this dynamic field.
