remove white space where entry header is on pages

Good day folks,

We are trying to create a new frontpage for the site. We are not using elementor, but the wordpress page builder.

We noticed a few things to get fix, but first we are trying to remove the entry header on the page we are developing as a frontpage. We used the option cover in the wordpress builder and we added the code below. Although it helped somehow, we still see a white space in between, where the entry header and title was.

.page-id-(number) .entry-header {
display:none !important;
}

.page-id-(number) .entry-content {
margin-top: 0 !important;
}

Could you give us a hand and tell us how to fix this issue please?

In advance, thank you for your help and interest.
