Very simple but I’m proud, it’s responsive!

speaking of my blog, does anyone know what I could do to make it work with something like rss.app to build a feed?

I can't figure it out for the life of me, if anyone would be super nice and check out my code for me that would be awesome thank you in advance! maybe it's a limitation of big cartel but I have no idea lol
