title: Strange Safari CSS bug with CSS gradients
body: <p><img src="https://i.stack.imgur.com/x44Yj.png" alt="bug"></p>
  
  <p>Hello,</p>
  
  <p>I've added a CSS gradient to this button but there appears to be a weird line appearing. Is there some way I can fix this?</p>
  
  <p>The CSS:</p>
  
  <pre><code>#view-content .billing-form #submit {
      background: #94c723; /* Old browsers */
      background: -moz-linear-gradient(top,  #94c723 0%, #6cb119 100%); /* FF3.6+ */
      background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#94c723), color-stop(100%,#6cb119)); /* Chrome,Safari4+ */
      background: -webkit-linear-gradient(top,  #94c723 0%,#6cb119 100%); /* Chrome10+,Safari5.1+ */
      background: -o-linear-gradient(top,  #94c723 0%,#6cb119 100%); /* Opera 11.10+ */
      background: -ms-linear-gradient(top,  #94c723 0%,#6cb119 100%); /* IE10+ */
      background: linear-gradient(to bottom,  #94c723 0%,#6cb119 100%); /* W3C */
      filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#94c723', endColorstr='#6cb119',GradientType=0 ); /* IE6-9 */
      border: none;
      border-top: 1px solid #a1d61a;
      -moz-border-radius: 3px;
      -webkit-border-radius: 3px;
      border-radius: 3px;
      color: #FFFFFF;
      font-size: 18px;
      line-height: 40px;
      padding: 0 70px;
      font-weight: bold;
      font-family: Arial, sans-serif;
  }
  </code></pre>
