title: How do I access web accessible resources in my content scripts css file in firefox?
body: <p>This is a fairly simple question. To access a web accesible resource that is declared in the manifest.json, we use the browser.runtime.getURL method in any content script javascript. <strong>How do we get an url to the web accessible resource in css?</strong></p>
  <p>Manifest:
  <code>&quot;web_accessible_resources&quot;: [&quot;resources/logo.jpg&quot;]</code></p>
  <p>JavaScript
  <code>browser.runtime.getURL(&quot;resources/logo.jpg&quot;)</code></p>
  <p>CSS
  <code>background: url(???)</code></p>
