I’m struggling to make my mobile version look good for all versions. It’s not centered and my columns are a mess. Here’s a link to my site: Webflow - Matt's Business Starter
The first shows that one of my columns is moveable and not centered, the second photo shows my intro header not centered when I zoom out on the mobile site.
It’s a much simpler layout to control and will make your life easier. Unless you have a really good reason you need that section set up in that specific way (which is not a typical layout).
You can see the parent Container is going horizontally across with 3 child divs for the headers. The only way you could make that work on mobile is to use Grid, because it allows you to move children to different cells at different breakpoints. However I would strongly recommend setting this up differently and actually using real columns, much easier to work with across screen sizes.
