What is a key consideration when implementing lazy loading for images in a responsive design?
Using appropriate srcset and sizes attributes is crucial for responsive lazy loading because: 1) It allows browsers to choose the most appropriate image size for the device and viewport, 2) Prevents loading unnecessarily large images on smaller devices, 3) Optimizes bandwidth usage and loading performance, 4) Ensures good visual quality across different screen sizes. When combined with lazy loading, this approach provides optimal performance by not only deferring image loads but also ensuring that when images are loaded, they're the most appropriate size for the user's context.
