title: Shopify background-image with css (doesn't show)
body: <p>My problem is that when trying to insert some kind of a background image in Shopify, it never shows anything.</p>
  
  <p>I have a navigation bar that has a pattern which the client wants and when I try to enable it, again nothing happens.</p>
  
  <p>The code I'm using on that css background line (from googling around) is</p>
  
  <pre><code>background:url( "{{'navBggreen.jpg' | asset_url }}")
  </code></pre>
  
  <p>I've also tried</p>
  
  <pre><code>background:url( {{'navBggreen.jpg' | asset_url }} )
  </code></pre>
  
  <p>and nothing. Tutorials or any kind of documentation is extremely scarce for Shopify so...</p>
  
  <p>Anyway, does anyone know how to get this working?</p>
