I am using Katie's template and am attempting to get my css to show up, however with how I am following the tutorial nothing is showing up and I can't figure out why. I took an edited version and just copied the code to try implement it into what the tutorial says to see if it was just how I was handling things. This is what the code looks like (please check link)

When I upload this in my description the code does go away but nothing changes and it goes back to default Lioden. It's driving me insane how I can't figure out what I'm doing wrong here. For this example I have changed nothing from the edited version of the template, just copied and saved it to my computer and put it into this.
