Question FloAuctions / ObsidianAuctions Layout

I'm trying to edit the language.yml file for the plugin so that when I start an auction, this is how it looks by default.



I've tried a few different things and either it doesn't work at all and reverts to default, or parts of it work. But then I go with those parts, and try to further remake the image, and it breaks. So, can anyone help me out here?
