title: Change background color of dropdown menu on hover
body: <p>I'm trying to change the submenu background color of a menu in its hover state. I've tried using firebug to find the relevant css classes but have only been partially successful.</p>
  
  <p>If you visit the site (<a href="http://www.yogaacademy.com.au/new/" rel="nofollow">http://www.yogaacademy.com.au/new/</a>) you'll see that there is both a grey and black background on hover. I want it to be completely black.</p>
  
  <p>It's a wordpress site using the woothemes canvas theme with some customizations. The html (below) is pretty standard, but the I haven't been able to figure out exactly where the relevant css is coming from: styles.css and css/ and custom.css in the canvas-child theme.</p>
  
  <p>Your help will be much appreciated.</p>
  
  <p>Thanks.</p>
