Slight horizontal scroll

My “published” site has a slight horizontal scroll. It is happening on both Chrome and Safari, but not on my iPhone. It is not happening editor mode so I can’t figure out what is causing the issue. Can anybody help. (This has been RESOLVED) I had a blank section that I used as a spacer and the width was set to 100vw but when I set it back to auto it got rid of the slight horizontal scroll.
