Build your lazy loading collection showcase website

User navigation typically is what triggers lazy loading images. In particular, when a user scrolls down on a page, that tells the browser to load the images that appear there.

For example, if a web page has an image that the user has to scroll down to see, you can display a placeholder and lazy load the full image only when the user arrives to its location.

To create a page loader, you simply need to: Create your HTML code to indicate what you want to use as your loader, e.g., an image or an icon. Then, style your loader page to your taste. Finally, create a JavaScript script that will fire up when the page is requested and then execute the code it contains.

Chrome and Firefox both support lazy loading with the loading attribute. This attribute can be added to elements, and also to elements. A value of lazy tells the browser to load the image immediately if it is in the viewport, and to fetch other images when the user scrolls near them.

Lazy loading is a technique for waiting to load certain parts of a webpage especially images until they are needed. Instead of loading everything all at once, known as eager loading, the browser does not request certain resources until the user interacts in such a way that the resources are needed.
