title: Using pure HTML and CSS in modal
body: <p>I found this modal <a href="http://codepen.io/imprakash/pen/GgNMXO" rel="nofollow">http://codepen.io/imprakash/pen/GgNMXO</a> pure html and css no js. It's all great and all but how can I make it trigger without using a button or link? I want it to pop up to welcome visitors once the website load.</p>
  
  <pre><code>&lt;div id="popup1" class="overlay"&gt;
  &lt;div class="popup"&gt;
      &lt;h2&gt;Here i am&lt;/h2&gt;
      &lt;a class="close" href="#"&gt;&amp;times;&lt;/a&gt;
      &lt;div class="content"&gt;
          Thank to pop me out of that button, but now i'm done so you can close this window.
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
