this template shows on mobile screens an enormous but unnecessary margin to the very top of the page. I found the css code that is responsible for this:
#container_header {
margin-top: 60px;
}
and changed it to
#container_header {
margin-top: 0;
}
I do not know the reason for this margin. It is consuming a significant part of a small mobile screen, where any inch is precious. I hope, setting it to 0px has no unexpected side effects.
Kind regards
Chris
