Horizontal space not working?

[HilaryP]

I'm trying to add a module under another module in Design Manager. When I previewed the addition of the new module under the exisiting one, I noticed there was virtually no space between the two, so I added a horizontal spacer. But, this appears to have done nothing. Ideas?

Hi @HilaryP - is there any way you could provide more context like a preview link?
