title: Input group - two inputs close to each other
body: <p>How can I make input group involves two inputs?</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;div class="input-group"&gt;
      &lt;input type="text" class="form-control" placeholder="MinVal"&gt;
      &lt;input type="text" class="form-control" placeholder="MaxVal"&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>This doesn't work, they are horizontal instead of inline</p>
