Lightense Images Tutorials and Examples

Import lightense.min.js

<script type="text/javascript" src="https://cdn.jsdelivr.net/gh/sparanoid/lightense-images@master/lightense.min.js"></script>

Insert some images in html

<p><img src="https://d349cztnlupsuf.cloudfront.net/railgun-logo.png" data-background="rgba(23, 29, 54, .8)"></p>

<p><img src="https://d349cztnlupsuf.cloudfront.net/almace-scaffolding-text-vertical.svg" data-lightense-background="rgba(255, 1, 180, .2)"></p>

Here is one thing you must notice:

data-background and data-lightense-background represent the backgroud when an image is zoomed. You can set value by rgba or rgb

Add event listener

<script type="text/javascript">
window.addEventListener('load', function () {
  Lightense('img:not(.no-lightense),.lightense');
}, false);
</script>

You should know:

not(.no-lightense): which means image zoom does not work on images with class no-lightense.

However, this library can not set zoom rate.
