Featherlight plugin: Styling the thumbnails

I am using the Gravcart and have install the featherlight plugin. The thumbnail border isn’t coming out the way I want it as you can see from the image below. The horizontal border is missing as depicted by the arrows. Where is the file to adjust this?

Is there any opportunity that you may share the URL to the site?

This is on a local server. I have figure it out the best way I know how.


.lightbox img {margin-bottom: 5px;}


<div class="lightbox">
	{% for images in page.media.images %}
	{{ images.lightbox(1024,768).cropResize(120,120).html( images.filename|replace({'-': " "}), images.filename|replace({'-': " "})) }}
	{% endfor %}
