Line block customisation

Hi there,

Based on my screenshots, I'd like a line to cross the width of the screen, as I've configured it at the bottom of the header, but I'd like this line to be part of the content of the section below the header so that it disappears when I scroll. So I tried adding a line in the section below the header but I couldn't customize it so that it is positioned where the line included in the header is. There is always an offset (see yellow area) whatever I try. As you can see on the screen shot that it can't be positioned any higher, even though it's configured in the high position. Is there a way of positioning a line exactly at the beginning of the block containing it?

Thanks a lot !
