Lock top bar - menu

Hi. It’s possible to lock the top bar at the page and not ever on top of the screen like now? I’ve problem with pics gallery.

If u choose first image it enlarges on top, if u go down with the page and select the last photo, the zoom go down the top bar, so you can’t look the entire photo. I hope i’ve explained well.
Best regards.

I’ve changed lightbox images effect now and it puts image on top, but however, I would like to tie the menu at the page. I would menu that disappears when you scroll the page.

Sure, you would need to add this to your custom CSS plugin:

.stuck {
  position: relative;

Thanx, it works.
Now Lightboxed images doens’t go under the top menu.
