Just finished my first profile theme!

I was originally going to do a pastel, light-themed profile but I messed up in putting one of the hexadecimal colour codes and it turned a dark red colour so I decided to go for something dark.
(It was also easier on my eyes as its 00:17 am for me).
I think I might keep this theme around for a while until I learn more CSS coding (i only know the basic stuff I was taught in school) but if anyone has any ideas for what my next theme should be let me know! (Also if you know any cool CSS coding let me know about that as well, I'm very inexperienced)
Goodbye for now!
p.s
I am an idiot who just spent the last 10 minutes being really confused about what error id made when trying to change the blog-posts background colour, I had done everything right except I had forgotten to put the # infront of the hexadecimal numbers so it wouldn't work. (◞‸◟；)
