Reduce White Gap below Caption of a Gallery Reel

I insert 3 Gallery Reels on my Website, with the controls below left. if i activate the Caption, there is a huge white Space below the Caption, that doesn't look very good. how can i reduce the white gap with css? thanks for your help. 

Can you share your website URL and the page location of this gallery? Thanks!

(site wide password too if your website isn't public)

yes, here you go: http://dachshund-perch-6het.squarespace.com/

you'll find a gallery with description and too much white space on: https://dachshund-perch-6het.squarespace.com/exhibitions

thanks for your help

I see the space, but unusually I can't tell why it's there. Are there any settings in the gallery section that you can change the padding? There's a minimum height of 100px.

no, there are no settings to change the padding. 

which element has a minimum height of 100px? if you change it via css it has affects on the white space?

i searched and inspected for this specific space element, i cannot find it. i think somehow there is a minimum height for the caption container. but i can't find the class where to change this.

so you see no solution on that issue?

Try adding to Design > Custom CSS

@media screen and (min-width:768px) {
body#collection-63e3ca963a2e9b3f9a400188 .gallery-reel-controls {
    bottom: 50px !important;
}
}
