I downloaded an HTML website template and converted it to a wordpress theme. I know wordpress requires a file called style.css (which came with my template). If I want to make my own custom styling in my wordpress site, is it best practice to just edit the style.css file? Or to create my own css file and add it in functions.php?
I know there's also a section in the wordpress editor to add custom lines of css but that seems dangerous to me as I don't know where it's putting that code.
