title: How do I change the background color for code block in jekyll?
body: <p>I'm playing with Jekyll, and have been able to change the background colour for my site. However, no matter which background or background-color properties I change in <code>_syntax-highlighting.scss</code>, I still get the same light grey background (even if I restart the jekyll server).</p>
  
  <p>None of the css/sass default files seem obvious to me for this, either.</p>
