title: CSS Mask-image won't work
body: <p>I am trying to mask image (with text shadow) using CSS property -webkit-mask-image.</p>
  
  <p>I understand that I can use background-clip however I need to do this using only mask-image</p>
  
  <p>property for some reason. However upon trying it out I was stack with some CSS codes.</p>
  
  <p>here's my CSS code: </p>
  
  <pre><code>#masking h1, span.mask-text {
      font-size: 230px;
      font-family: 'Lilita One', sans-serif;
      text-align: center;
      margin: 0 auto;
      padding: 0;
      -webkit-text-fill-color:transparent;
      position:absolute;
      left: 100px;
  
  
  }
  
  #masking h1 {
      text-shadow: 3px 3px 0px #34495e;
      z-index:2;
  }
  
  span.mask-text {
         -webkit-mask-image: url('http://halloweenmaternitycostumes.com/wp-content/uploads/2014/11/paper.jpg') no-repeat center center;
     background-size: cover;
      z-index:5;
      -webkit-transition:all 0.7s ease;
     -moz-transition:all 0.7s ease;
       -o-transition:all 0.7s ease;
          transition:all 0.7s ease;
  
  }
  
  span.mask-text:hover{
  cursor: pointer;
   -webkit-mask-image: ('http://halloweenmaternitycostumes.com/wp-content/uploads/2014/11/paper-hover.jpg') no-repeat center center;
     background-size: cover;
   z-index:5;
  
  }
  span.mask-text:after {
      content: 'Mask Text';
      text-transform: uppercase;
  }
  </code></pre>
  
  <p>Here's an image what I am trying to do:</p>
  
  <p><img src="https://i.stack.imgur.com/UP5aU.jpg" alt="enter image description here"></p>
