HTML
HTML is short for Hypertext Markup Language. HTML holds the content we see on a page (text, images) and defines the structure and order in which the content appears.
CSS
Short for Cascading Style Sheets, this language controls the look and feel of a webpage. It can change the layout of items on a page, colors, fonts, and even animate elements!
JavaScript
This programming language is responsible for user interaction. For example, when the user clicks a button and sees a change in the browser, this action is controlled by JavaScript.
