Can you just tell me what the problem is?
no one is going to wade through your errors for you
pick one – fix it – in most cases it will fix several as they are usually cascading errors
a good place to start is with whatever you did last before it borked
also, unclosed tags – especially <div>
tags will bork the layout
How can I Just reset all of the CSS?
Does Anyone know how to just reset the CSS to it’s original state?
If you want to reset the CSS to it’s original state, just replace your current style.css file with the one from the theme.
How can I find the original style.css from the theme?
It will be with your theme download. This theme isn’t in the WP theme repository, so you couldn’t have used the built-in theme installer. This means you have a file/folder, most likely a *.zip file, with all the original theme files somewhere. This is where the style.css file will be.
I dont have that becuase my friend downloaded it for me.
Ask your friend where they got it, and then you’ll be set.
