title: Modal Window with scroll bar
body: <p>So, I have a modal window in a website that I'm devloping.</p>
  
  <p>The modal is made out of pure CSS, to open it and close it I have javascript functions wich change the css elements to make the modal show/hide.</p>
  
  <p>CSS of the modal:</p>
  
  <pre><code>&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 &gt; div {
      position: relative;
      margin: 10% auto;
      padding: 5px 20px 13px 20px;
      border-radius: 10px;
      background:white;
      display: table;
  }
  .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;
  }
  
  .btnEncomendarProduto {
      background-color:#D60E12;
      color:white;
      border-radius:5px;
      font-size: 12px;
      white-space:normal;
      cursor:pointer;
      text-transform: initial;
      border:1px solid #D60E12;
      margin-top:3px;
  }
  &lt;/style&gt;
  </code></pre>
  
  <p>So the problem is when I have a something that displays too much information on the modal, this happens: <a href="https://i.stack.imgur.com/MIo2X.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/MIo2X.png" alt="enter image description here"></a></p>
  
  <p>So I think I need a scroll bar on the div inside the modal. How can I do that?</p>
  
  <p>Thank you.</p>
