'd like to add a line inbetween each of the different posts on any page to help break them up and help users distinguish between the different posts, but I don't know how to do it.

Could anyone help me please? I'm comfortable with different colours, line styles, and stuff like that. Just need the foundation code to set it up to begin with.

Here's the site:

Managed to fix it.
