What are the best practices for native lazy loading?

Native lazy loading is a technique to defer loading offscreen images and iframes until they are needed. Best practices include using the 'loading' attribute, optimizing images, and ensuring proper fallback for browsers that do not support it.

Can you explain how the 'loading' attribute works?

The 'loading' attribute can be set to 'lazy', 'eager', or 'auto'. When set to 'lazy', the browser will load the image or iframe only when it is about to enter the viewport, improving performance.

What are some common mistakes to avoid with lazy loading?

Common mistakes include not using the 'loading' attribute, lazy loading critical images, and failing to test across different browsers.

How can I test if lazy loading is working correctly?

You can test lazy loading by using browser developer tools to monitor network requests and check if images load as you scroll down the page.
