Can't find-out how to position my header

Hey ya’ll
-I’m on the Portfolio project and have a header I can’t position.
–I’m trying:

h1 {
position:fixed;
top:40px;
}

and that moves it down also but un-centers it and I want it centered.
—I’m also trying this:

h1 {
top:40px;
}

but that doesn’t do anything at all. I think I need a ‘position’.
Anyway, I can’t figure out how to bring the header down from the top of the page.
Here’s my page:

lol I figured it out.
I used:

h1{
margin-top: 10%;
}

and that did it. hahahah
