Add Space Between Posts

Hi all,

I have read a few posts on this topic but can’t make any of the solutions help, and all of the previous threads are closed.

I need help adding space at the end (or beginning) or each of the posts in my blog: https://www.aldenleonard.com/blog. Currently, they all run together. I have tried modifying margins, adding in code, and nothing seems to work. Can someone take a look and point me in the right direction?

I am using the theme WPFolio, but it’s slightly modified for my content. I looked at the WPFolio support site but it referred me back here.

Thanks everyone!
