Add space in between columns!

Hey so I am trying to figure out how to add a space in between 2 columns so it doesn’t look like the words are all one column.

Here is what the page looks like.

It is only on this page that I am needing this. Not sure if that makes a difference or not. Also I am just using [one_half][/one_half][one_half][/one_last_half]. If I can just add something in on this page around that it would be the easier for me.

Thanks so much!
