<div id="cars" lazy-observe></div>
document.querySelector('#cars').addEventListener('lazy-loaded', function(event){
    const target = event.target;
    target.textContent = "Hey I'm lazy";
});

Class


  • You can set a class lazyattr wich be transform in lazyloaded after the element is loaded (work on the pointer and parent)
  • You can make a beatiful skeleton loader with lazy-skeleton, lazy-skeleton-corner and lazy-skeleton-top class

Skeletons


  • To set a skeleton loader on an image pls set it on his parent. After you need to put lazy-animation-pointer="#parent" on the image to remove it after load.
  • Set a skeleton loader on a div with lazy-background will automatically remove it after load.
