title: Bulge side of div, cut into side of div effect in CSS

  <p>I am looking to create two shapes in CSS.  The first one, the one on the left, I am close to making, but my shape goes out too far.</p>
  
  <p>The second shape, I am struggling with completely.</p>
  
  <p>Is there anyway to replicate these shapes?  Is there anyway to do it without the use of Psuedo elements/as one div only?</p>
  
  <p>The goal is to use CSS animation to make the first shape into the second, <strong>so I do not believe SVG is an option</strong>. </p>
  
  <p>The <code>div</code> should start at shape one, and gradually transition into shape two. I'm having issues getting the bulge to not stick out so far, with my method.</p>
  
  <p>HTML</p>
  
  <pre><code>&lt;div id="one"&gt;&lt;/div&gt;
  &lt;div id="two"&gt;&lt;/div&gt;
  </code></pre>
  
  <p>CSS</p>
  
  <pre><code>div {
      width: 80px;
      height: 80px;
      background: black;
      margin: 60px;
      position: relative;
  }
  
  #one:before {
    content: "";
    display: block;
    position: absolute;
    border-radius: 55%;
    width: 80px;
    height: 80px;
    background: black;
    left: 0;
    top: -34px;
  }
  </code></pre>
