loading=lazy to HTML images for the Browser to load them as the user scrolls
For my blog and personal site, I wanted images to lazy load in as you scroll down the page. This makes for a better reading experience when there are lots of images on a single page. It also stresses out my server less, as only the images people actually scroll to are ever downloaded.
In the past I've used various JS frameworks and tool to accomplish this, but now we can do it natively in HTML!
All you need to do is add the
loading="lazy" attribute to your images! MDN Attribute Link
CanIUse shows that there is ~93% compatibility for the
loading attribute when applied to images. So for
most of my use cases this will do perfectly!
loading can also be applied to
iframes but the browser
compatibility for this is a bit lower at ~81%. [Mobile Safari on older versions is most of the difference here]
