title: How to prevent line break before H3?
body: <p>I am trying to use <a href="https://stackoverflow.com/questions/21909732/html-css-multilevel-nested-lists-numbering">this</a> solution to make a multilevel numbered list outline.</p>
  
  <p>The problem is that I need top level list items to begin with H3 elements and what I get is something looking like</p>
  
  <pre><code>1
  My heading
  1.1 My subelement
  </code></pre>
  
  <p>While, needless to say, what I want is</p>
  
  <pre><code>1 My heading
  1.1 My subelement
  </code></pre>
  
  <p>I have checked - the problem is in H3 - it prepends itself with line break naturally. How do I disable this?</p>
