Modify spacing/ padding

I’d like to add space under the’ add to cart’ button and where the additional product option text area begins. I’m also using the section feature of your plugin and find the space between the section title and the textarea label is too much.

I guess custom CSS is required, I’m not able to share the direct link, but I am using the THE7 theme.

Do you have plans for adding padding options to your plugin in the future?

Thanks!
