HTML, CSS, and JavaScript are the foundational technologies for web development.

  • HTML (HyperText Markup Language) provides the structure and content of web pages. It defines elements such as headings, paragraphs, images, links, and forms. HTML is like the skeleton of a website.
  • CSS (Cascading Style Sheets) is the language used to style and visually arrange the HTML content. It controls colors, fonts, spacing, and the overall layout of the page. CSS is like the skin, hair, and clothing of a website.
  • JavaScript (JS) is the programming language that brings interactivity and dynamic functionality to a website. It handles animations, pop-up menus, form validation, and fetching data from the back-end without needing to reload the page. JavaScript makes the site come alive.
