Progressive Image Loading Inspired By Medium.com – Pure Media

Pure Media is a tiny JavaScript library that applies a Medium.com like progressive loading effect to images within the document.

Easy to integrate with the lazysizes library that provides a user-friendly progress image lazy loading for your web app.

How to use it:

1. Insert the stylesheet ‘pure-media.css’ in the head section of the document.

<link rel="stylesheet" href="dist/css/pure-media.css" />

2. Insert the JavaScript file ‘pure-media.css’ after the lazysizes library.

<script src="lazysizes.min.js"></script>
<script src="dist/js/pure-media.js"></script>

3. Embed images into the document following the HTML structure as follows:

<figure class="graf-figure">
  <div class="aspectRatioPlaceholder">
    <div class="aspectRatioPlaceholder-fill"></div>
    <div class="progressiveMedia lazyload" data-width="3820" data-height="2762">
      <img class="progressiveMedia-thumbnail" src="thumbnail.jpg" />
      <img class="progressiveMedia-image lazyload" data-srcset="1.jpg 1920w, medium.jpg 767w" />
    </div>
  </div>
</figure>
