Remove unwanted space below widget

I created a Widget on Page with separate linked images and used some CSS to align them the way I liked. Only now there is a ton of empty space between the images and my text. I’ve tried setting a max height to remove the space but no luck. Is there a way to remove this space?

Here’s a link to the site so you can see what I’m attempting to describe.
