title: Generating PDF from CSS and HTML, more distance between @page @top-center and content
body: <p>I generate a PDF from CSS and HTML with ITextRenderer. But I dont know how to get more distance between <strong>9. Some text</strong> and the border-bottom of the @top-center.</p>
  
  <p>This is my styling:</p>
  
  <pre><code>@page {
    counter-increment: page; 
    margin-top: 80px;
    @top-center { 
      font-size: 9pt;
      content: "Page Header";
      border-bottom: 2px solid black;
      white-space: pre; 
      margin-bottom: 40px;
    }
  }
  </code></pre>
  
  <p>This is how it looks now:
