Thank you so much for the quick reply! Related — if you have time — I have had a terrible time finding where/how to make changes in the stylesheet so there is not so much space in between paragraphs within the body. I feel like I’ve played around with everything but am not seeing any differences.

As you have experienced it’s best not to edit the original stylesheet.
Use a custom css plugin or create a child theme.

This is the default setting.

.entry p {
    margin: 20px 0;
}
