title: Background-image + Fixed + NOT Transparent
body: <p>This is my css:<br></p>
  
  <pre><code>body {
    background-image: url('mybackground.jpg');
    background-repeat: no-repeat;
    background-attachment: fixed;
    background-size: 100%;
  }
  </code></pre>
  
  <p>But when I scroll down, the background image is transparent &amp; this is not what I want.(my background image is like a header image, just like this website but the header if fixed).<br>
  What should I do? <br>
  Any suggestions?</p>
