          Demo:<br />
          An accessible Modal Window with JavaScript &amp; CSS
          <b>Note</b> - There's a new version of this script that you can find on my <a href="https://github.com/scottaohara/accessible_modal_window">github page</a>.

          This modal window is made with plain old semantic mark-up, CSS and
          a very little bit of JavaScript.

          Check out the <a href="https://codepen.io/scottohara/pen/lIdfv">source code on codepen</a> to see how it works!

        <form action="#">
          <label for="test" class="label">Label for Input</label>
          <input type="text" id="test" class="input" />

          <label for="test2" class="label">Label for Second Input</label>
          <input type="text" id="test2" class="input" />

          <label for="test3" class="label">Label for Third Input</label>
