@VirtualVictoriaa I made a slight visual difference to the original theme that I would like you to look over. The background image is tinted darker in the middle instead of the whole thing. I did it because I was able to actually figure it out. I couldn't figure out how to do it the original way (using Bootstrap 5), but I think the new way actually looks pretty good.

It might be useful to test it out with an image instead of the plain gray background. Just to see what it looks like

I added a tag field to the theme dependency, so that it is now pointing at a specific version, instead of at the newest commit. This will make it so that it won't change every time we update https://github.com/btc-raspberrypiclub/cleaner-blog-jekyll.
