CSS — Responsive Design

Responsive design ensures that your website looks good on all devices, including phones, tablets, and desktops. CSS uses media queries to apply different styles based on the screen size. This allows you to change font sizes, hide or show elements, and adjust layouts for smaller or larger screens. With responsive design, you don't need separate websites for mobile and desktop users. It improves user experience and accessibility while making your site future-ready.

@media (max-width: 600px) { h1 { font-size: 18px; } .sidebar { display: none; } }
