CSS (Cascading Style Sheets) makes websites look beautiful. Think of it as interior design for your web pages - choosing colors, layouts, and styles.
HTML builds the house structure (walls, rooms). CSS is the interior designer who chooses paint colors, furniture placement, lighting, and decorations to make it beautiful.
What CSS Does
- 🎨 Colors: Text, backgrounds, borders
- 📏 Layout: Positioning elements on the page
