title: How to center a card in semantic-ui?
body: <p>I have implemented owl slider for cards, I tried to simulate as mobile device, it looks the card is not properly centered.</p>
  
  <p><a href="https://i.stack.imgur.com/7mzgv.png" rel="noreferrer"><img src="https://i.stack.imgur.com/7mzgv.png" alt="enter image description here"></a></p>
  
  <p>I've tried all UI grid and other center classes, they didn't work.</p>
  
  <p>Here is my HTML</p>
  
  <pre><code>&lt;div class="owl-carousel"&gt;
  
      &lt;div class="ui card"&gt;
          &lt;div class="image dimmable"&gt;
              &lt;div class="ui blurring inverted dimmer transition hidden"&gt;
                  &lt;div class="content"&gt;
                      &lt;div class="center"&gt;
                         &lt;div class="ui teal button"&gt;Ver más sobre Circulo K&lt;/div&gt;
                      &lt;/div&gt;
                  &lt;/div&gt;
              &lt;/div&gt;
              &lt;img src="../assets/images/stores/circulok.jpg"&gt;
          &lt;/div&gt;
  
          &lt;div class="content"&gt;
              &lt;div class="header"&gt;Circulo K&lt;/div&gt;
                  &lt;div class="meta"&gt;
                      &lt;a class="group"&gt;Meta&lt;/a&gt;
                  &lt;/div&gt;
                  &lt;div class="description"&gt;Descripción Corta&lt;/div&gt;
              &lt;/div&gt;
  
              &lt;div class="extra content"&gt;
                  &lt;a class="right floated created"&gt;Arbitrary&lt;/a&gt;
                  &lt;a class="friends"&gt;&lt;/a&gt;
              &lt;/div&gt;
          &lt;/div&gt;
  
     &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>How do I that?</p>
