I've been working on and editing a casino-themed CSS for my profile since 6 AM, but every time I finish it ends up failing.

--felt: #0b4d31;

--felt-light: #17895a;

--felt-dark: #06331f;

--wine: #4a0a14;

--red: #b3122b;

--red-dark: #6d0a18;

--gold: #e0b84a;

--gold-dark: #a8822a;

--ivory: #f6f0df;

--black: #0c0c0c;

--display: 'Abril Fatface', 'Playfair Display', Georgia, 'Times New Roman', serif;

--body: 'Libre Baskerville', Georgia, 'Times New Roman', serif;

Because of this, every time I finish and save PUFF, all of this disappears.
