MelonCipher Ashymations RavenRainProductions - so, I took a look at each of your codes and it looks like the problem is that certain tags (e.g. <i> tags for Font Awesome icons) aren't being closed properly.
Technically this is an issue with the HTML - but I recognise that the behaviour is not easy to understand, and it's not immediately clear why it's happening (+the editor used to handle these unclosed tags just fine). It started happening after I updated code parsing yesterday, to fix a different bug (HTML tags inside comments made the editor freeze).
I have partially rolled back yesterday's update while I figure out a better solution for that other bug. Those codes work for me now, but let me know if it's still not working!
