body: <p>everyone please advise, I have an array with images, and I've created a mapping content, however I can not put a Background Image, in styles of a component. Other array objects is properly working</p>
  <pre><code>{DlCards.map((mdlcard) =&gt; {
      return(
      &lt;Grid
          item
          xs = {mdlcard.grid_xs} 
          sm = {mdlcard.grid_sm} 
          md = {mdlcard.grid_md}
          container
          justify = 'space-between'
          style   = {{
              width:      '25%', 
              marginTop:  60,
              backgroundImage: {mdlcard.background}
              
          }}&gt;
  </code></pre>
