Remove nav bar CSS not working neither globally or locally

BB Theme
1

Hello,
I’m new to Beaver Builder, but can’t seem to remove the top nav bar for a landing page I’m building.
I’ve done some searches here on the forums, and even when adding the CSS below the nav bar still shows.

.fl-page-nav {
  display: none;
  visibility: hidden;
}
.fl-page-nav-wrap {
    display: none;
}

I’ve tried adding the CSS both to the global theme, and on my specific page, with no luck.
The page is at fuelebylumen.com/main-page (as I saw it being asked for in some threads)

Thank you in advance for any help you can provide!

Hello,
Yes, the link is the key to diagnosis; it’s the patient! I can’t seem to access anything at that URL. It says:

This site can’t be reached

Check if there is a typo in fuelebylumen.com.
