Less space under HeaderMedia on homepage

For now I just want a static homepage with a little text, so I have none of the blocks enabled. This leaves a large gap between the header image and the text. I've already added:

.page-id-4 .singular-content-wrap, .page-id-4 #content .wrapper {
	padding-top: 0;
}

which has helped a little but ideally I'ld want the space to be equal to that below the paragraph of text. https://sportplatformwaddinxveen.nl/ Kind regards, David van Balgooi
