title: VueJS v-bind:style for background-image: url()
body: <p>According to <code>VueJS</code> docs: </p>
  
  <blockquote>
    <p><code>&lt;div v-bind:style="{ color: activeColor, fontSize: fontSize + 'px' }"&gt;&lt;/div&gt;</code></p>
  </blockquote>
  
  <p>I've tried several patterns: </p>
  
  <pre><code>&lt;div v-bind:style="{ background-image: url(item.img), }"&gt;&lt;/div&gt;
  
  &lt;div v-bind:style="{ 'background-image': url('item.img'), }"&gt;&lt;/div&gt;
  
  &lt;div v-bind:style='{ backgroundImage: "url(item.img)", }'&gt;&lt;/div&gt;
  </code></pre>
  
  <p>But the results are not valid for the HTML <code>style</code> attribute.</p>
  
  <p>Any ideas?</p>
