title: Centered, equal width, columned items using flexbox
body: <p>I have a column of 4 items. All the items have different widths due to different content. Using flexbox, Does anyone know how I can make all the items the same width as the largest item while keeping them all centered please?</p>
  
  <p>Here's what I have at the moment.</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.container {
    display: flex;
    flex-direction: column;
    justify-content: center;
    align-items: center;
  }
  
  .item {
    background: #efefef;
    border: 1px solid #ccc;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="container"&gt;
    &lt;div class="item"&gt;
      &lt;h3&gt;Item 1&lt;/h3&gt;
      &lt;ul&gt;
        &lt;li&gt;Lorem ipsum dolor sit amet&lt;/li&gt;
        &lt;li&gt;Lorem ipsum&lt;/li&gt;
        &lt;li&gt;Lorem ipsum dolor sit amet, consectetur adipiscing&lt;/li&gt;
        &lt;li&gt;Lorem ipsum&lt;/li&gt;
        &lt;li&gt;Lorem ipsum&lt;/li&gt;
        &lt;li&gt;Lorem ipsum&lt;/li&gt;
      &lt;/ul&gt;
     &lt;/div&gt;
  
    &lt;div class="item"&gt;
      &lt;h3&gt;Item 2&lt;/h3&gt;
      &lt;ul&gt;
        &lt;li&gt;Lorem ipsum&lt;/li&gt;
        &lt;li&gt;Lorem ipsum&lt;/li&gt;
        &lt;li&gt;Lorem ipsum dolor sit amet&lt;/li&gt;
        &lt;li&gt;Lorem ipsum&lt;/li&gt;
      &lt;/ul&gt;
    &lt;/div&gt;
  
    &lt;div class="item"&gt;
      &lt;h3&gt;Item 3&lt;/h3&gt;
      &lt;ul&gt;
        &lt;li&gt;Lorem ipsum&lt;/li&gt;
        &lt;li&gt;Lorem ipsum&lt;/li&gt;
        &lt;li&gt;Lorem ipsum&lt;/li&gt;
        &lt;li&gt;Lorem ipsum dolor sit amet&lt;/li&gt;
        &lt;li&gt;Lorem ipsum dolor sit amet&lt;/li&gt;
        &lt;li&gt;Lorem ipsum dolor sit amet, consectetur adipiscing elit.&lt;/li&gt;
      &lt;/ul&gt;
     &lt;/div&gt;
  
    &lt;div class="item"&gt;
      &lt;h3&gt;Item 4&lt;/h3&gt;
      &lt;ul&gt;
        &lt;li&gt;Lorem ipsum&lt;/li&gt;
        &lt;li&gt;Lorem ipsum&lt;/li&gt;
      &lt;/ul&gt;
    &lt;/div&gt;
  &lt;/div&gt;</code></pre>
