Making a title screen/ centering a main screen

superwholockland

Do you know if it's possible to center the main menu to the very center? Whenever I try with the

<center></center>

code, what it does is center it to the middle of the playable area, not counting the sidebar, which makes it set to the right.
I set the sidebar to invisible using

body.sad #ui-bar {
	display: none;
}

which makes all the text disappear from it, but still sets it to the right, like it's invisible but still there
My questions are, I guess,
1 Is there a way to completely center the main menu to the center?
2 Is there a way to remove the sidebar completely?
3 Is there a way to make a set title screen that doesn't include the sidebar at all?

Oh sweet jesus i finally figured it out, after much digging

for those curious, i set the UI bar to invisible using

body.sad #ui-bar {
	display: none;
}

and then I found someone trying to shift the UI bar to the right, having to compensate for moving the passages to the left, and modified their code until it worked

#passages {
	margin-left: 0;
	margin-right: 17em;
	padding: 0;
	border: none;
}
