What are HTML & CSS?

Every website you've ever visited is built from just two simple ingredients. Watch a blank page turn into a real website — right before your eyes.

HTML = Structure 🧱
Hello!
Welcome to my website.
CSS = Style 🎨
Section 1

HTML is the skeleton 🦴

Just like your bones hold your body together, HTML holds a webpage together. It doesn't make things pretty — it just says what's on the page.

HTML gives structure to everything:

<h1> Makes a big heading
<p> Makes a paragraph of text
<img> Shows an image
<button> Makes a clickable button
<a> Makes a clickable link
<ul> Makes a list
<h1>Hello!</h1>
<p>Welcome to my website.</p>
<button>Click Me</button>

Hello!

Welcome to my website.

👆 This is HTML alone — it works, but it looks plain. That's normal! HTML's job is structure, not beauty.

Section 2

CSS is the outfit & decoration 👕🎨

HTML = the house structure 🏠   |   CSS = the paint, furniture, and decoration 🎨

Before CSS

Hello!

Welcome to my website.

After CSS

Hello! 👋

Welcome to my website.

Same HTML. Same words. CSS added colors, fonts, spacing, and shadows — nothing else changed.
