There are plenty of guides covering what you might want to do in your welcome message with fancy HTML or CSS, but as far as I can tell - there’s no thread dedicated for asking how to do something. Well, now there is!
Reply with something that you’ve always wanted to do in your welcome message, but couldn’t figure out how and I’ll do my best to help you out - and if it isn’t incredibly basic, I’ll make a video explaining how it works!
Background music - just use this code:
<audio autoplay> <source src="../gym.mp4" type="audio/mpeg"> </audio>
../gym.mp4 can be changed to any audio URL, the ones built into the game are listed here
