Hi!
I’ve used webflow a lot in work - mainly just from an editor/CMS point of view.
So I have been playing around and trying to create my own websites for a while now!
I am creating this one for a friend - but I realise it will not work on a phone whatsoever!
I am assuming I have messed around with the section/containers too much…

Is there any easy fix for this? Any suggestions are helpful as I’m not sure what to do next without undoing all the design I’ve done so far!!

Thanks,
Leah-Clare
