title: How to set image width and height when we use url() in css
body: <p>I have implemented collapsible in my page. I want to put down arrow img rather than '+' on right side of collapsible</p>
  
  <p>I can set img rahter than '+' by using url() as follows.</p>
  
  <pre><code>button.accordion:after {
      content: url("download.jpg");
      color: white;
      font-weight: bold;
      float: right;
      margin-left: 5px;
  }
  </code></pre>
  
  <p>Now, how can I set width and height of that image if I have used url() of css.
  Need your valuable thoughts. Thanks in advance!</p>
  
  <p>Sorry, but I wont consider it as a duplicate question. I have to set image but not as a background-img. </p>
