Responsive Web Design
Media Queries
Media queries allow CSS to adapt styles based on screen size.
Example:
<!DOCTYPE html> <html> <head> <style> body { background-color: lightblue; } @media (max-width: 600px) { body { background-color: lightcoral; } } </style> </head> <body> <p>Resize the browser to see the background change.</p> </body> </html>
