You’ve definitely used Chrome Extension Lighthouse, Google PageSpeed Insights, or GTmetrix to evaluate your WordPress site’s speed if you want to make it run faster. Defer offscreen is a warning that you may have seen. I’ll describe how lazy loading your Images may be used to address “defer offscreen images” in this post.
What does defer offscreen images mean?
Let’s start define the fold first. The area of the screen that is visible as soon as you land on a page is known as the fold. It’s the first material you see; you don’t need to browse down or do anything else. This section is termed above the fold because it is immediately at the top of the page. The first element that the browser must render in order for users to engage with the content is the most crucial component of the page.
However, all of the material that can only be seen by scrolling down is labeled below the fold. It doesn’t matter as much when a page is loading, as you might assume.
By delaying the loading of non-critical assets that are “below-the-fold,” or in other words, anything that is not now in the browser viewport, lazy loading is a strategy for increasing initial page performance and payload. In WordPress, deferring offscreen pictures essentially means waiting for the images that aren’t yet visible to load.
