Beginner Guide to HTML, CSS, and JavaScript

Every website starts with a few core building blocks. For the web, those building blocks are HTML, CSS, and JavaScript. They are often learned together because each one has a different role in building a complete user experience.

What HTML Does

HTML stands for HyperText Markup Language. It defines content such as headings, paragraphs, images, links, forms, and page sections.

What CSS Does

CSS stands for Cascading Style Sheets. It controls colors, typography, spacing, positioning, responsiveness, and the overall visual layout of a webpage.

What JavaScript Does

JavaScript is the programming language that adds behavior to the page. It powers sliders, form validation, dropdown menus, API calls, search features, and many other interactive elements.
