HTML (HyperText Markup Language) is the standard markup language for creating web pages. It provides the structure and content of websites by using a system of tags and elements to tell web browsers how to display text, images, and other media.

CSS (Cascading Style Sheets) is used to style and layout web pages — for example, to alter the font, color, size, and spacing of your content, split it into multiple columns, or add animations and other decorative features. CSS helps separate content from presentation.

JavaScript is a programming language that enables interactive web pages. It is an essential part of web applications and can update content, animate images, sort tables, and much more. JavaScript makes web pages interactive and engaging by responding to user events like clicks, inputs, and page loads.
