Can someone help me out? Struggling

Hey there guys! I just started Wolvden recently, and so just started CSS as well. If you look at my profile, I'm working on a CSS there- and the stuff I wrote for the chatbox just didn't work. I have it written in my CSS file, but it never was put onto my profile... I went into Inspect Element to see what was going on, went to console, and found these errors.

I had written these same things in other CSS files, which work fine. But this one CSS comes back with these errors and just completely ignores it.

These are the error messages I got. Please let me know if you recognize them or understand what they mean!! I'm a CSS baby and have no idea what the basic vocabulary is of CSS and these statements are like a foreign language to me. I looked up the problem on different websites, and people have just said to turn off your AdBlock or to disable "Allow JS Source maps" in the settings, but neither fixed it for me. I'm not sure what to do and I'm afraid I'll just have to start over completely.

my error messages:

That… is weird, and admittedly I know very little about Javascript, but the element inspector console isn’t looking at CSS. If you have an error in CSS the browser will just ignore it; it won’t make error messages like this.

Would you be willing to send me the CSS file, or at least the sections you’re using to edit the chatbox? (I’m not staff or anything but I’m pretty good with CSS. Promise I won’t steal anything :P) If you’ve been able to edit the rest of your profile without issue, it’s possible you’ve missed a closing bracket or the chat has weird overrides or something.
