title: How do I change the font in markdown pandoc?
body: <p>I am writing a document in markdown, and I read that I could change the font to Arial like this:</p>
  
  <pre><code>---
  fontfamily: arev
  ---
  </code></pre>
  
  <p>But it did not work. But when I try to change the font to Times, it's working fine</p>
  
  <pre><code>---
  fontfamily: times
  ---
  </code></pre>
  
  <p>So how do I change the font to Arial?</p>
