A jQuery plugin that adds random noise to the background of an element.

You can try the interactive demo.

• jQuery

Just download the repository and link to the local minimized script:

<script src="noisy/jquery/jquery.noisy.min.js"></script>

Alternatively, include it from cdnjs.com:

<script src="//cdnjs.cloudflare.com/ajax/libs/noisy/1.1/jquery.noisy.min.js"></script>

An example showing all parameters would be the following:

$('body').noisy({
    intensity: 0.9,
    size: 200,
    opacity: 0.08,
    fallback: 'fallback.png',
    monochrome: false
});

But since all parameters are optional you can just use it like this:

$('body').noisy();

What's wrong with using an image?

1. Bandwidth cost
   Due to the random nature of background images with a noisy overlay, compression usually isn't very effective. With this 1 KB script you can generate images up to 300 KB without loading for even a second. Saving bandwidth costs and loading time.
2. Development speed
   Trying out an image with a different noise opacity involves a much smaller amount of steps by just updating a parameter than changing and saving the image in Photoshop.
3. Flexibility
   By generating the background image in javascript, one does not need to rely on the webserver being able to serve static files for it. With generated favicons etc. a static files serving webserver becomes optional.

I'd be flattered if you'd flattr this :)
