Menu button opening a empty page on mobile

Topic summary

Mobile navigation on ecoperiod.pl opened an empty sliding panel on phones; the issue existed in an imported theme. A screenshot was provided showing the blank menu drawer.

Resolution (confirmed by OP): add CSS in theme.liquid just above to force the off‑canvas menu drawer to appear on small screens.

  • Scope: only on mobile (max-width: 767px)
  • Fixes:
    • div#menu-drawer { height: 100vh !important; }
    • .menu-open div#menu-drawer { transform: translate(0%) !important; visibility: visible !important; }

Outcome: Applying the CSS makes the menu drawer visible and correctly slide in when the menu is opened on mobile. No further issues or open questions; thread resolved.

When you go to ecoperiod.pl on mobile and click on the menu button a empty slider opens.

I imported this theme and the issue was already there.

Can anyone help please?

Found the solution:

theme.liquid > find at the bottom of the code > put this code above :

@media screen and (max-width: 767px) { div#menu-drawer { height: 100vh!important; } .menu-open div#menu-drawer { transform: translate(0%)!important; visibility: visible!important; } }
