I'm writing some html and css to create a webpage. On the left of the page is a nav section. At the top is a header, below which is a 'main' section containing text in various sections, and below that is a footer. I have managed to get the header and footer to remain fixed as desired and also get the main section to scroll between the header and footer. The links in the nav are supposed to let the user jump to a section of main as required. However, when clicking on introduction, the introduction section gets positioned at the very top of the page (hidden under the header) where as I would like it to jump to its position just below the header. I've tried various combinations of setting top and position:absolute in main but without success. Can anybody help? The html and css are below:
index.html:
<!DOCTYPE html>
<html lang="en" >
<head>
<meta http-equiv="Content-type" content="text/html;charset=utf-8" />
<title>John Doe</title>
<link type="text/css" rel="stylesheet" href="homepage.css">
<style type="text/css">
</style>
</head>
<body>
<header id="top">
<h1>
<dl>
<dt>
John Doe
</dt>
<dd>
<img src="logo.jpg" alt="Logo" >
</dd>
</dl>
</h1>
</header>

It may be necessary for you to reduce the window size of your browser in order to see the issue I've described to ensure that main cannot fit on the screen all at once.
