title: Xaringan Title Slide
body: <p>In xaringan, I want to add a background in the title slide.
  I've managed to do that following <a href="https://github.com/yihui/xaringan/wiki/Title-slide" rel="noreferrer">Yihui's</a> instructions.</p>
  
  <p>This works, except <strong>I loose the default fonts (Yanone Kaffeesatz)</strong>. </p>
  
  <p>YAML:</p>
  
  <pre><code>---
  title: "My title"
  subtitle: "My subtitle"
  author: "Me Myself"
  date: "01/01/2012"
