Gap under shortcode

Hi,

I am using this plugin and I find it has some neat features. I however cant use a lot of them because I get extra padding under the short code which makes it look weird.

To be clear I am 99% clueless when it comes to CSS but after speaking to the support for my theme it seems the issue is with the pluhin or its .css.

Now I have no idea what I am doing but I tried to take a shot in the dark and paste this in the custom CSS form in hopes that I could overwrite it so the bottom margin would be basically non existent.

.su-carousel {
position: relative;
margin-bottom: 0em;
overflow: hidden;
-webkit-backface-visibility: hidden;
-moz-backface-visibility: hidden;
-ms-backface-visibility: hidden;
-o-backface-visibility: hidden;
backface-visibility: hidden;
z-index: 1;
}

It did not seem to work, I will continue to experiment with it to see if there is an easy fix but in all honesty I could use some help. All I want is to be able to reduce the gap that ends up below the content, it gets really excessive with the carousel.
