Responsive Image Tips
- sizes attribute: Tells the browser how wide the image will be at different viewport sizes
- srcset: Provides multiple image sources for the browser to choose from
- WebP: Modern format with better compression - use with <picture> for fallback
- Lazy loading: Defer off-screen images to improve initial page load
- Retina (2x): Higher resolution for high-DPI displays
- Test: Use browser DevTools to verify correct images are loaded
