What does "Lazy-Loading" mean?

Lazy-Loading is a method used to speed up the loading of the items that show up above-the-fold on a web page. It does so by delaying the loading of the items (particularly images) that show up below-the-fold, so they don't compete with the items one wants to display first. Here is an example of lazy-loading something within an <iframe> tag:

<iframe src="huge-image.jpg" loading="lazy"></iframe>
