CSS - Making it Pretty

📖 Lesson

What is CSS?

CSS (Cascading Style Sheets) is the language that defines how HTML elements look.

HTML = what's on the page. CSS = how it looks.

h1 {
color: #00d4aa;
font-size: 32px;
}

This says: all <h1> headings will be green and 32px large.

Basic CSS properties

Modern CSS tricks

With CSS you can create amazing effects:

Gradients - smooth color transitions
Hover effects - changes on mouse hover
Shadows - depth and 3D feel
Flexbox - easy element alignment

Don't be afraid to experiment! Changing one CSS value can completely transform the look. Tell AI "change the color to blue" and watch it change.
