How to hide menu and breadcrumbs on mobile display
I've successfully added CSS code to hide the left sidebar (region) and breadcrumbs on a folder and its galleries...when viewed on my PC.
However, both still display when I view it on mobile devices (Samsung S10 and iPhone). I've perused the forum and tried some of the @media suggestions to no avail.
Here's how the folder looks on my mobile display. The sidebar shows above the gallery thumbnails and the breadcrumbs still display.
