Divs doesn't align as I want when published in mobile/tablet view

Hi everyone,

Im having trouble with my site… In computer landscape everything looks OK, and it looks fine in every other landscape too. But if i publish it to the webflow.io, inspect it as a mobile device… everything is of-set to the left or it doesnt align to center, and you can even scroll sideways for some reason. what am i doing wrong?!

Kind regards,

a tired and confused webflow-noob
