homepage layout for dropbox menu is weird

I'm writing a homepage and I need a dropbox menu, so I found a demo for dropbox menu from googling. But the codes did not work properly even if I applied the demo. Its layout is quite ridiculous.

The #menubar is parallel with #site_content but I intended to place #memubar that contains dropbox menu virtically followed by #site_content. Please refer below source code for detail.

HTML code:

<!DOCTYPE HTML>
<html>

<head>
  <title>main</title>
  <meta name="description" content="website description" />
  <meta name="keywords" content="website keywords, website keywords" />
  <meta http-equiv="content-type" content="text/html; charset=windows-1252" />
  <link rel="stylesheet" type="text/css" href="style/style.css?ver=1" />
</head>

<body>
  <div id="main">
    <div id="header">
      <div id="logo">
<h1><a href="index.html"><span class="logo_colour">Homepage</span></a></h1>
        <h2>Test</h2>
      </div>
      <div id="menubar">
        <ul id="menu">

          <li class="selected"><a href="index.html">Menu1</a></li>
          <li>
        <a href="#">Menu2&#9662;</a>
                <ul class="dropdown">
                    <li><a href="#">Home</a></li>
                    <li><a href="#">About</a></li>
                    <li><a href="#">Contact</a></li>
                </ul>
          </li>

          <li><a href="#" class="ellipsis">Memu3</a></li>
          <li><a href="#" class="ellipsis">Menu4</a></li>
        </ul>
      </div>
    </div>
    <div id="site_content">
            <h1>Welcome to Homepage<br/>
We welcome you. <br/><br/><br/></h1>
    </div>
    <div id="footer">
        <section align="left" class="visitor bg_white">
