Lazy Loading for Images and Iframes

There is a new attribute in town. It's the loading attribute which can be applied to the img element and the iframe element. This can provide the perception of a quicker loading web page when you set the loading attribute to the value "lazy" on img and iframe elements that are not initially in the browser viewport. The resource is only requested when the web page visitor scrolls near the element. See https://web.dev/native-lazy-loading and https://web.dev/iframe-lazy-loading for more info.
