Syntax Error - Uploading Fonts

I've been watching a couple Squarespace videos on how to do small customizations on my website via the Custom CSS section and I type in the code exactly and it constantly gives me the Syntax Error on Line 1.

Not sure what I'm doing wrong?

Here's the code I was trying out.

Thanks

There is a syntax error because a URL is not CSS.

This is not a solution to your particular issue but an example of what a ruleset using the URL shown might look like.

@font-face {
 
  font-family : 'Louize Display';
  src : url( https://static1.squarespace.com/static/5e9d0db99e1a4f768cdede33/t/65f8aeef44414778b30f29b1/1710796527609/Louize+Display+-+Regular-205TF.otfhttps://static1.squarespace.com/static/5e9d0db99e1a4f768cdede33/t/65f8aeef44414778b30f29b1/1710796527609/Louize+Display+-+Regular-205TF.otf) format("opentype");
  
  }

If you are following a tutorial of some kind you should come across some code that looks similar to the above. Also there will be more rulesets to actually apply the font where you want. The previous code is just defining the font so it can be used.

Just to note. A feature of custom files is that you can click on one and it will add a URL into the Custom CSS field. You then need take that added URL and cut and paste it into the right location in your CSS.
