air-load-image v2.0.0

Air load image

Lazy loading of images and the background when scrolling.

Delay before checking the visibility of the element on the viewport, which provides more flexible configuration of the plugin.

Installation

Via npm:

$ npm install npm install air-load-image

Usage

Include jQuery library (slim build is recommended) and the Air Load Image plugin's script at the bottom of the page.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script src="air-load-image.min.js"></script>

Embed your images and background images use the data-air-img attribute, which will auto change to the standard src attribute as the image(s) enter the viewport on vertical page scrolling.

<img class="_air-load-image" 
     src="placeholder.jpg" 
     data-air-img="demo-img.jpg">

<div class="_air-load-image" 
     style="background-image: url('placeholder.jpg');" 
     data-air-img="demo-bg.jpg">
</div>

Active the image lazy load plugin with just one line of code.
