Hovering over the image will remove the filter effect.
1. Add the downloaded css file path to the head of your document:
<link href="path/to/cssco.css" rel="stylesheet" type="text/css">
2. Add the filter to your image element using the relevant CSSCO classes:
<div class="cssco cssco--c1">
Unfortunately, IE & Edge browsers, as well as Opera Mini do not support filters and blend modes.
Safari (desktop & IOS ) does not support the hue, saturation, color, and luminosity blend modes, but this should not affect the CSSCO filters much, if at all.
