Dear all,
I am working on two shopify stores for clients. On both stores I setted up the value of page-width to 1280px and as default the margin: 0 auto. I have already checked padding which is horizontally 0 !important. Anyways in one store I have a horizonztal margin of 80px and in the other store something very different. It should be in both stores the same.
Sorry you are facing this issue, it would be my pleasure to help you.
