Much to much empty space between embedded video and text

Hi,
as you can see on https://a-casaccio.cestudio.de/rustico (a site under construction) there’s much to much vertical space between the embedded video and the text or next gallery.How can this be fixed?

Cheers
Chris

Hi Chris

That space is fully occupied by the Iframe you are using on the page, space is inside the Iframe, so, we cant change it by custom css
