Best jQuery Lazy Load Plugins & Tutorials with Demo

Asynchronous boundary detection – lazy-loading, infinite scroll, and more.Whether you’re lazy-loading images, implementing infinite-scroll, or avoiding an ex-lover… it’s important to set boundaries.

yall.js is a featured-packed lazy loading script for <img>, <picture>, <video> and <iframe> elements. It works in all modern browsers including IE11. It uses Intersection Observer where available, but falls back to scroll, touchmove, resize, and orientationchange events where necessary. It can also monitor the DOM for changes using Mutation Observer to lazy load image elements that have been appended to the DOM after initial page render, which may be desirable for single page applications. It can also (optionally) optimize use of browser idle time using requestIdleCallback. To optimize decoding of <img> lazy loading for simple src and srcset use cases, yall.js uses Image.decode where available to decode images asynchronously before adding them to the DOM.
