Overview of web development technologies: HTML, CSS, JavaScript, and PHP.

Web development is the process of building and maintaining websites and web applications. It includes everything from simple static pages to complex dynamic applications. A full-fledged web application often combines front-end technologies (what users see) and back-end technologies (how the system works behind the scenes).

Four fundamental web technologies:

  • HTML – Structures web content.
  • CSS – Styles and formats the content.
  • JavaScript – Adds interactivity and dynamic behavior.
  • PHP – Handles server-side logic and database interactions.
