title: Can I create a div with a Curved bottom?
body: <p>So I'm working on a site and I was wondering if it's possible to, purely using HTML5, CSS3 (and JavaScript if needed), make a div with a curved bottom, so it will look practically like this:</p>
  
  <p><a href="https://i.stack.imgur.com/ZfM0a.png" rel="noreferrer"><img src="https://i.stack.imgur.com/ZfM0a.png" alt="enter image description here"></a></p>
  
  <p>Or can this only be done using a background image?</p>
  
  <pre><code>&lt;body&gt;
      &lt;div class="navbar navbar-fixed-top"&gt;
          &lt;div class="navbar-inner"&gt;
          &lt;ul class="nav"&gt;
              &lt;li&gt;&lt;a href="#"&gt;Home&lt;/a&gt;&lt;/li&gt;
          &lt;/ul&gt;
          &lt;/div&gt;
      &lt;/div&gt;
  &lt;/body&gt;
  </code></pre>
