Web Technologies

Websites are the backbone of the Internet, and they are all built using three main technologies.

  • HTML is used for filling web pages with content and for shaping their structure.
  • CSS is intended for styling, positioning and appearance.
  • JavaScript makes it possible to add functionality, that is, responses to user actions.

These three basic technologies are not enough to create a website, in fact. You also need to learn about code editors, version control systems, bundlers, frameworks, libraries, hosting arrangements and other concepts.
