What are the best practices for lazy loading images on a website?

The best practices for lazy loading images include using the 'loading' attribute, implementing a placeholder, and ensuring images are loaded as they come into the viewport.

Can you explain how the 'loading' attribute works?

Sure! The 'loading' attribute can be set to 'lazy' on image tags, which tells the browser to load the image only when it's about to enter the viewport.

What are some common pitfalls to avoid when implementing lazy loading?

Common pitfalls include not using placeholders, lazy loading above-the-fold images, and failing to test across different devices and 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 only when they are in view.
