title: Why :before cannot be seen in safari?
body: <p>I have a code which works brilliant in Chrome:</p>
  
  <pre><code>#menu ul {
  list-style-position: inside;
  list-style-type: none;
  display: block;
  margin: 0 auto;
  padding: 0;
  }
  #menu li {
  font-size: 11px;
  width: 95px;
  display: inline-block;
  vertical-align: top;
  position: relative;
  }
  #menu li a {
  color: black;
  text-decoration: none;
  }
  #menu li a img {
  opacity: 0;
  filter: alpha(opacity=0);
  -moz-opacity: 0;
  position: absolute;
  top: 0;
  left: 22px;
  margin: 0 auto;
  -webkit-transition: opacity 0.2s linear;
  -moz-transition: opacity 0.2s linear;
  -o-transition: opacity 0.2s linear;
  -ms-transition: opacity 0.2s linear;
  }
  #menu li a:hover img {
  opacity: 1.0;
  filter: alpha(opacity=100);
  -moz-opacity: 1.0;
  }
  #menu li a:before {
  content: "";
  display: block;
  background: url('../images/greece.gif') no-repeat center;
  width: 50px;
  height: 50px;
  margin: 0 auto;
  opacity: 1.0;
  filter: alpha(opacity=100);
  -moz-opacity: 1.0;
  -webkit-transition: opacity 0.2s linear;
  -moz-transition: opacity 0.2s linear;
  -o-transition: opacity 0.2s linear;
  -ms-transition: opacity 0.2s linear;
  }
  #menu li.news a:before {
  background: url('/images/menu/4.gif') no-repeat center;
  }
  #menu li a:hover:before {
  opacity: 0;
  filter: alpha(opacity=0);
  -moz-opacity: 0
  }
  #menu li a span.image-title {
  display: block;
  padding: 5px;
  }
  #menu li:hover a, #menu li.current.active a {
  color: red;
  }
  </code></pre>
  
  <p>I do not want to use such crazy code, but I have no other way 'cause I'm working with joomla 2.5</p>
  
  <p>So what I have as a result...
  In firefox doesn't work opacity transition. No, itworks, but in a strange way... Tolerably.</p>
  
  <p>In Safari :before are not shown at all!</p>
