CSS not being applied in pages

[ABurkas]

Hello eveyone,

I am new to github. I’ve been following tutoials etc on how to set up pages. Now, i’m trying to move my codepen HTML and CSS over here. HTML is working, but CSS is not being applied.

I’m obviously doing something wrong. But I can’t figure it out.
