Unable to center page, header tag and section tag not working

Hi,
I a few things that are not working as I (newbie) expect from what I have coded.  I'm trying to get my h1 and h2 tags to sit to the right of the img in my header tag but it shows below the image. Also, I have a section tag with css setting a border for it but the border won't show. I'm also trying to center the page but that isn't working either. The html and css is below. Thank you very much.

******** HTML **************************

<!DOCTYPE HTML>
	<head>
		<title>Building Contractor</title>
		<link rel="stylesheet" type="text/css" href="styles.css" />
	</head>
	
	<body>
			<header>
				<img src="imgs/InnInKeyWestFlorida_bnr.png" />
						<h1>Hello World</h1>
						<h2>Hello World</h2>
			</header>
			<nav>
				<ul>
					<li><a href="#">Home</a></li>
					<li><a href="#">Projects</a></li>
					<li><a href="#">Services</a></li>
					<li><a href="#">Contact Us</a></li>
				</ul>
			</nav>
			<section>
				Here is the section element
			</section>
			<footer>
				<h3>This is the footer</h3>
			</footer>
	</body>
	
</HTML>

For the border you are missing a semi colon after the width
section {
      margin: auto auto;
      height: 400px;
      width: 200px;
      border: 5px solid black;
}

Wrap your H1 and H2 in this
<div class="head-container">
</div>


and add this css
.head-container {
    display:inline-block
}

Thank you. Why doesn't my margin-right and margin-left center the page?

GaryCommented:
To use margin:0 auto you need to have everything between your body tags wrapped in a container and then give that container a set width e.g.

<div id="container">
...everything else here
</div>


CSS
#container {
width:900px;
margin:0 auto;
}
