Hello,
I had previously requested assistance on a separate thread a few weeks ago regarding this issue, which was partly resolved but unintentionally caused an additional issue for the page when it is viewed in mobile. The thread is here: https://kriesi.at/support/topic/custom-css-changes-to-blog-entry-large-image-no-sidebar/
I added the CSS in the quick CSS section of the enfold theme settings, but I believe I need additional CSS in order to prevent the code from working in mobile view. In mobile, the content is shifted up and either obscures a menu (on blog entry) or is obscured by the header/menu (on home page).
I have quite a bit of code in Quick CSS already (including code for mobile and desktop specific sections) so if needed I can provide login credentials for anyone to take a closer look.
