title: Extjs 4.2 - gradient background for menus using sencha cmd
body: <p>I would like to create a gradient background color using sencha cmd</p>
  
  <p>here is what I have tried :</p>
  
  <pre><code>.#{$prefix}-menu-body{
  @include background-image(linear-gradient(#47607E, #35475B));
   }
  </code></pre>
  
  <p>I have placed it under </p>
  
  <blockquote>
    <p>sass\src\menu\Menu.scss</p>
  </blockquote>
  
  <p>and run a package build.</p>
  
  <p>I do not see any change in the background of my menus.</p>
  
  <p>I would also like to know if I can use the CSS Variables to do that?</p>
