Elementor header on top of lightbox

Hi,

When I open my photos in a lightbox, some of the photos are not visible due to my header being on top of it. Is there a way to offset the lightbox from the top of the site so the toprow of images also becomes visible?
Or if the photos could show on top of the header, that would also work.
