Hi, this was bugging me too for such a long time! After playing around for a while though, I've managed to obtain useful and consistent results suitable for my purposes so maybe it will help others too? It's super simple, and adjustable too:
Add the following code to the custom CSS section:
#page .content {
padding-top: 10vh;
}
This will cause contented to move down on EVERY page, regardless of first section type. The background image of the first section (if applicable) will also reposition itself accordingly, and the good part is that the "10vh" will be responsive across all devices (you can increase or decrease this depending on your needs).
Hope this helps as a temporary workaround!
