title: bootstrap 5 alpha 2 card deck example not showing like it is in documentation
body: <p>I inserted this example for a card desk and thought it would show like its shown in the docs. But it isn't. <br>https://stackpath.bootstrapcdn.com/bootstrap/5.0.0-alpha2/css/bootstrap.min.css - I am using Bootstrap 5 alpha 2. Has the card layout changed ?
  <br>
  It is showing as three rows instead of 1 row with 3 columns. Do we need to insert grid based HTML too wrapping the card-deck ?</p>
  <pre><code>&lt;div class=&quot;card-deck&quot;&gt;
    &lt;div class=&quot;card&quot;&gt;
      &lt;img class=&quot;card-img-top&quot; src=&quot;...&quot; alt=&quot;Card image cap&quot;&gt;
      &lt;div class=&quot;card-body&quot;&gt;
        &lt;h5 class=&quot;card-title&quot;&gt;Card title&lt;/h5&gt;
        &lt;p class=&quot;card-text&quot;&gt;This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.&lt;/p&gt;
        &lt;p class=&quot;card-text&quot;&gt;&lt;small class=&quot;text-muted&quot;&gt;Last updated 3 mins ago&lt;/small&gt;&lt;/p&gt;
      &lt;/div&gt;
    &lt;/div&gt;
    &lt;div class=&quot;card&quot;&gt;
      &lt;img class=&quot;card-img-top&quot; src=&quot;...&quot; alt=&quot;Card image cap&quot;&gt;
      &lt;div class=&quot;card-body&quot;&gt;
        &lt;h5 class=&quot;card-title&quot;&gt;Card title&lt;/h5&gt;
        &lt;p class=&quot;card-text&quot;&gt;This card has supporting text below as a natural lead-in to additional content.&lt;/p&gt;
        &lt;p class=&quot;card-text&quot;&gt;&lt;small class=&quot;text-muted&quot;&gt;Last updated 3 mins ago&lt;/small&gt;&lt;/p&gt;
      &lt;/div&gt;
    &lt;/div&gt;
    &lt;div class=&quot;card&quot;&gt;
      &lt;img class=&quot;card-img-top&quot; src=&quot;...&quot; alt=&quot;Card image cap&quot;&gt;
      &lt;div class=&quot;card-body&quot;&gt;
        &lt;h5 class=&quot;card-title&quot;&gt;Card title&lt;/h5&gt;
        &lt;p class=&quot;card-text&quot;&gt;This is a wider card with supporting text below as a natural lead-in to additional content. This card has even longer content than the first to show that equal height action.&lt;/p&gt;
        &lt;p class=&quot;card-text&quot;&gt;&lt;small class=&quot;text-muted&quot;&gt;Last updated 3 mins ago&lt;/small&gt;&lt;/p&gt;
      &lt;/div&gt;
    &lt;/div&gt;
  &lt;/div&gt;
