title: CSS circular image at any size
body: <p>I am creating a circular image with CSS. </p>
  
  <p>When my image is 200px x 300px, it's not a perfect circle:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.circular {
    margin: auto;
    width: 200px;
    height: 300px;
    border-radius: 150px;
    -webkit-border-radius: 150px;
    -moz-border-radius: 150px;
    background: url(http://i.stack.imgur.com/S1ZCs.jpg) no-repeat;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="circular"&gt;&lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>Here is a <a href="http://jsfiddle.net/gfn2ots9/" rel="nofollow">jsFiddle</a> as well.</p>
  
  <p>Is there a way to make a perfect circle when the width and height are different sizes? If I set this to 300 x 300 it's a perfect circle, but I need it to be in a perfect circle when the image is 200 x 300.</p>
