I've just finished this CSS for myself and I added it to my Den Description but for some reason it isn't showing up. It all looks as intended in a live CSS editor but when I try saving it in my den description it just reverts back to default.

I have no idea what I'm doing wrong, but I know I probably made some mistakes in the CSS document but it all looked fine in the live editor so I gave up trying to perfect it behind the scenes.

This is what I've been trying to put in the den description (without asterisk):
<*link rel="" type="text/css" href="https://dl.dropbox.com/s/fikz0p32ddboh2kmgc3yo29/liodenpinkthing.css?rlkey=vf9ze2bc6kzy38x7dzrs71qk1&dl=0" />

and this is the link:
https://www.dropbox.com/scl/fi/kz0p32ddboh2kmgc3yo29/liodenpinkthing.css?rlkey=vf9ze2bc6kzy38x7dzrs71qk1&dl=0

I was following Katies tutorial but it got a little bit confusing at the link bit because my link was different to the example. I checked to see if anyone else had the same problem as me and tried some of their solutions but none of them worked.

If someone could solve this for me that would be amazing.
