Thanks that’s very helpful!
Yes, I’m thinking of the space between the lines of text. But the other 2 things you mention would be nice to know also.
I’m guessing they are all in this style.css file? Can I ask — do Devs normally edit this file from the WP dashboard, or do they use FTP to d/l it, make the changes, then re-up it?
I’d like to follow your best practice. Thanks
