Awesome background images for web pages.


It is recommended that you replace latest with a fixed version name to prevent your pages being interfered by breaking changes.

You can load the file (minified by default) from jsDelivr

<script async src="https://cdn.jsdelivr.net/npm/32ae08ef@latest/loadBackground.js"></script>


<script async src="https://unpkg.com/32ae08ef@latest/loadBackground.js"></script>

There are even more choices in China, but the speed and reliability cannot be guaranteed, and they may deliver outdated files.


<script async src="https://unpkg.zhimg.com/32ae08ef@latest/loadBackground.js"></script>


<script async src="https://npm.elemecdn.com/32ae08ef@latest/loadBackground.js"></script>

New Feature

Now You can assign to window._imgPlace to customize where to load the background image, which will be displayed behind document.body by default.

const imgPlace = document.getElementById('example');
window._imgPlace = imgPlace;

const divName = 'example';
window._imgPlace = imgPlace;


This file is expected to work well with the latest version of Chrome / Firefox. If not, please contact us.
