CSS
Domain: Internet & Web
🎯 Motivation
Cascading Style Sheets - controls how web pages look: colors, fonts, layout, animation.
📋 Concrete Example
CSS: ‘h1 { color: blue; font-size: 24px; } .button { background: green; border-radius: 5px; }’. The browser applies these styles. Headings are blue, buttons are green with rounded corners.
🔗 Analogy
CSS is like interior design - the frame (HTML) is there, but CSS chooses the paint colors, furniture style, and lighting. Same frame, completely different look with different CSS.
