Reducing space between paragraphs

Hi, any help will be much appreciated.

How do I reduce the space between paragraphs for my pages and blog posts? Im using Fresh News theme from Woo themes.

My website is https://www.juzzwright.com. If you have a look at the ‘about juzz’ page you will see what i mean about too much paragraph spacing

It says in the custom.css file

Instructions:

Add your custom styles here instead of style.css so it
is easier to update the theme. Simply copy an existing
style from style.css to this file, and modify it to
your liking.

Thanks
