For custom CSS you need to use the following format as explained in our guide:
<style type="text/css" data-photoslurp-css-id="widgetContainerID">
#widgetContainerID .elastislide-carousel ul li a img {
border: 10px solid black !important;
}
</style>
Or linking to an external CSS file such as:
<link rel="stylesheet" data-photoslurp-css-id="widgetContainerID"
href="css/custom.css">
Note: The Photoslurp logo and all trademarks may not be removed from any widget without the prior permission from Photoslurp.
