Hi there,
Thank you for reaching out!
I understand that you’d like to increase the space between the price and the add to cart button.
The quickest way to achieve that is via some custom CSS code but CSS is usually site-specific.
There are some suggestions in this thread:

These support documents/articles explain how CSS code can be written:

If you will not be able to write the code yourself – please provide a link to your product page and we’ll be happy to take a look.
