How do I remove huge gap of space between Collection Item elements

I have a collection item, which has two child elements: 1 image, and 1 div that houses text and a button. I can’t seem to remove the space between the image and that div. There is no padding or margin for the image. And the div has some margin and padding, but not large enough to account for the gap of space above it. Please see the image below to see the huge gap in space between Project Details and the image above it.
