Single post in Site Skins: How-To, and Helpful CSS

This is a thing that HAS to be added to its section, it's like the twentieth time I've seen someone asking why aren't stacked fields working and smeone correctly answering that you have to select a berry first. It's a bit annoying tbh, I'm subscribed to the thread in case there are new cool CSS, but but later the notices here are either someone asking for the stacked fiends or someone who didn't read something in the first post. Maybe it needs a little rework? At least, it needs the part about the berry as it seems to confuse a lot of people.
