  var btn = document.getElementById("myBtn");
  
  var span = document.getElementsByClassName("close")[0];
  
  btn.onclick = function() {
    modal.style.display = "block";
  }
  
  span.onclick = function() {
    modal.style.display = "none";
  }
  
  window.onclick = function(event) {
    if (event.target == modal) {
      modal.style.display = "none";
    }
  }</code></pre>
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.modal {
    display: none;
    /* Hidden by default */
    position: fixed;

    padding-top: 100px;
    /* Location of the box */
