How to adjust many layers next to each other?

If you plan on having multiple layers next to each other, on their Row element you should turn off Full Width.

This way as you make the screen smaller, the columns will start breaking into new rows.

Columns cannot be center aligned, they can only stay on the left. If you don't want this kind of breaking to happen, increase your breakpoints to avoid it. Then for smaller views you could use the Duplicate and Hide on options of the Row, to show a different Row on smaller screens.

That way for your new Row you could turn Full Width back on, and use its Wrap after setting.

The Wrap after setting is device specific, so you can set a different value for phones.
