Fonts (Not Really Working)

Hello Khan Academy! I just happened to find out that some fonts on Khan Academy don't work. What I mean is that whenever I try doing fonts like "monospace" on coding, it doesn't work. Only a few fonts work and I can list them out for you: "papyrus", "kristen itc", lucida console, castellar, gigi, gabriola, and maybe more. I want more fonts to work and I love decorating stuff. Without fonts, no decorating! I'm pretty upset with this problem and I want to have a better Khan Academy...

I know it's probably not Khan Academy's fault about the fonts, but if you can fix it... thanks so much! That's all I want, more fonts! I really love Khan Academy and have been staying for more than a month. Khan Academy is a great resource to learn about coding, math, and more... but the fonts are way off. I hope you listen to my problem and have a fantastic and most wonderful day! :)
