title: Bootstrap CSS classes wildcard
body: <p>I want to target all of the columns inside a Bootstrap container so I can give then a similar style. For example:</p>
  
  <pre><code>&lt;div class="container unique"&gt;
    &lt;div class="row"&gt;
      &lt;div class="col-md-3"&gt;&lt;/div&gt;
      &lt;div class="col-md-3"&gt;&lt;/div&gt;
      &lt;div class="col-md-3"&gt;&lt;/div&gt;
      &lt;div class="col-md-3"&gt;&lt;/div&gt;
    &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I can target this with CSS:</p>
  
  <pre><code>.unique .col-md-3{...}
  </code></pre>
  
  <p>but what I want to do is when I have many different <code>col-*</code> elements, to target them all together.</p>
  
  <p>I tried this:</p>
  
  <pre><code>.unique .col-*{...}
  </code></pre>
  
  <p>but it didn't work.  Can I do this with CSS? </p>
