title: Modal not working in IE10, but works fine in other browsers
body: <p>I am creating a modal dialog based on a CSS only approach from the online example below.  It works great in IE 11, Chrome and Firefox, but in IE 9 and IE 10, the modal doesn't work.  </p>
  
  <p>In IE 9 and IE 10, you can't click any of the content - in this example it's a link, but in my own implementation I have several buttons on the page, only one of which actually opens the modal, and they all can't be clicked - I'm thinking because the modal might be sitting overtop of the buttons somehow, even though it's invisible.</p>
  
  <p>Can anyone please help me figure out why this isn't working in IE 9 and IE 10, and whether there's anything I can do to fix it in those browsers?  Also, I'm a little new to web development.  Is there any tools that can analyze your markup and CSS to see if there's any compatibility issues with older browsers?  Maybe a tool like that could have helped me here.</p>
  
  <p>Here is the JSFiddle</p>

  <p>Or here is the code you could just save into an HTML file and load into the browser.</p>
  
  <pre><code>&lt;!doctype html&gt;
  &lt;html lang="en"&gt;
  &lt;head&gt;
    &lt;style&gt;
    .modalDialog {
      position: fixed;
      font-family: Arial, Helvetica, sans-serif;
      top: 0;
      right: 0;
      bottom: 0;
      left: 0;
      background: rgba(0, 0, 0, 0.8);
      z-index: 99999;
      opacity:0;
      -webkit-transition: opacity 400ms ease-in;
      -moz-transition: opacity 400ms ease-in;
      transition: opacity 400ms ease-in;
      pointer-events: none;
    }
  
    .modalDialog:target {
      opacity:1;
      pointer-events: auto;
    }
  
    .modalDialog &gt; div {
      width: 400px;
      position: relative;
      margin: 10% auto;
      padding: 5px 20px 13px 20px;
      border-radius: 10px;
      background: #fff;
      background: -moz-linear-gradient(#fff, #999);
      background: -webkit-linear-gradient(#fff, #999);
      background: -o-linear-gradient(#fff, #999);
    }
  
    .close {
      background: #606061;
      color: #FFFFFF;
      line-height: 25px;
      position: absolute;
      right: -12px;
      text-align: center;
      top: -10px;
      width: 24px;
      text-decoration: none;
      font-weight: bold;
      -webkit-border-radius: 12px;
      -moz-border-radius: 12px;
      border-radius: 12px;
      -moz-box-shadow: 1px 1px 3px #000;
      -webkit-box-shadow: 1px 1px 3px #000;
      box-shadow: 1px 1px 3px #000;
    }
  
    .close:hover {
      background: #00d9ff;
    }
    &lt;/style&gt;
  &lt;/head&gt;
  &lt;body&gt;
    &lt;a href="#openModal"&gt;Open Modal&lt;/a&gt;
    &lt;div id="openModal" class="modalDialog"&gt;
      &lt;div&gt;
        &lt;a href="#close" title="Close" class="close"&gt;X&lt;/a&gt;
        &lt;h2&gt;Modal Box&lt;/h2&gt;
  
        &lt;p&gt;This is a sample modal box that can be created using the powers of CSS3.&lt;/p&gt;
        &lt;p&gt;You could do a lot of things here like have a pop-up ad that shows when your website loads, or create a login/register form for users.&lt;/p&gt;
      &lt;/div&gt;
    &lt;/div&gt;
  &lt;/body&gt;
