title: Why don't fenced code blocks in Markdown appear in a monospace font when Doxygen generates HTML?
body: <p>When I run the following through Doxygen</p>
  
  <pre><code>~~~{.cpp}
  int main(int argc, char** argv)
  {
     printf("Hello world!\n");
  }
  ~~~
  </code></pre>
  
  <p>The HTML output has the expected C++ syntax highlighting but the font is no different from normal text. Do I need to specify a font in the Markdown source? If so, how do I do that? Is this something that would be remedied by updating Doxygen? I'm using v1.8.5.</p>
