- DISREGARD (FOUND ANSWER) -

I've been working on a CSS code for my den and in all the tutorials I've found they say to paste the code from Notes to a Dropbox file. Is there a specific type of file I should convert my code to, like PDF or Dropbox Pages or Google Doc or something? I've tried replacing "www" with "dl." and still nothing works when I try to paste it into my den code.

Hopefully this makes sense :/
