Yes, we are sure. If this would be possible to be done with custom css then we would give you such solution obviously. However, what you ask for, requires files customization what in reference to Item Support Policy is not allowed. So if you want to modify files and don't know how, you need to contact with your web developer.

the sidebars appears always after the content and it is not possible to move them above on mobile.
Thanks for understanding!
