title: Custom <input type="file"> not working in IE
body: <p>I'm trying to use a custom &lt; input type="file" > button. This works in chrome and FF. How do I make it work in IE 10 and above?</p>
  
  <p><strong>The problem in IE is that the browse box is not opening.</strong></p>
  
  <p>html:</p>
  
  <pre><code>&lt;button type="button" id="fileT"&gt;&lt;input type="file" id="file"&gt;&lt;/button&gt;
  </code></pre>
  
  <p>css:</p>
  
  <pre><code>#fileT{
      overflow: hidden;
      position: relative;
  }
  #fileT input {
      position: absolute;
      opacity: 0.1
  }
  </code></pre>
