you can also shove text and images in there.

look at the help guides at the top of the group, and check out beginner css/html on web3schools

also inspect (pressing Q on most browsers or right clicking and pressing inspect) is gonna be your best friend! itll help you see how the code works, what css classes you need to change things, and lets you tinker around without actually saving anything (as soon as you refresh all of the changes you made will be gone. so just copy paste what you wrote if you want to save it)

writing from scratch is super daunting, even for people that know what they're doing, so I'd recommend looking at other people's code and trying to understand bit by bit what they wrote. That's how i learned lol
