Thanks, Steven. I added in the link color and !important to additional CSS to make the link colors work, so all good there now, and the code worked for text size as well.
On the width, I’m referring to the post content. I’d like my post content to max out at something like this page has, but am not sure what to add to additional CSS to make that happen. https://pinchofyum.com/bangkok-coconut-curry-noodle-bowls
