this is a handmade cohost archive page, made by @haraiva based on @fish's cohost corner page. i've borrowed the css from ayu (as linked on this cohost post) and expanded on it a little bit. you can see my code (and steal it) here.
which means you can probably copy the source code for this wholesale and start making your own posts if you want. this whole thing is very minimally commented right now but if you're comfortable with html this should be pretty easy to tinker with.
here's what post body would look like. i'm intrigued as to why/how the cohost version of atkinson hyperlegible is just a little lighter in weight than what's given to you on good ol' google fonts. did they modify it? maybe. that's cool. anyway here's what a link looks like. yay!
asking something. asking something. hello.
wow. well here's a response. if you even care.
and here is... an image! this is actually the first post i've made on cohost.
