Alright! I got it working. Thanks, everyone.
I put it in under “sidebox,” which is like “sidebar,” in layout.css, which is basically like my stylesheet. The stylesheet imports layout.css, which is not accessible in my Editor on WordPress, so I have to download it on Filezilla, edit it, and upload it again directly onto the server.
If I go through and change it all to div.sidebar, would that help? I added the widget code into my stylesheet, but the bullet points are still there.

The link to the designers’ site is at the bottom. It’s not a common one, it seems. The code’s a bit quirky in places.
