HTML & CSS
The Foundation of Every Website
HTML and CSS are the building blocks of the web. Every website you visit uses them. They're the perfect starting point for learning web development.
What are HTML & CSS?
HTML
HyperText Markup Language defines the structure and content of web pages. It tells browsers what to display: headings, paragraphs, images, links, buttons, and more.
Think of it as the skeleton of a website.
CSS
Cascading Style Sheets controls the appearance of web pages. It defines colors, fonts, spacing, layouts, animations, and everything visual.
Think of it as the skin and clothing of a website.
Together, HTML and CSS work as a team: HTML creates the elements, CSS makes them beautiful. Add JavaScript for interactivity, and you have a complete website!
