title: Best approach to divide Bootstrap grid columns
body: <p>I have divided my <a href="https://en.wikipedia.org/wiki/Bootstrap_%28front-end_framework%29" rel="nofollow noreferrer">Bootstrap</a> grid columns following way.</p>
  
  <pre><code>&lt;div class="container-fluid"&gt;
      &lt;div class="row"&gt;
          &lt;div class="col-md-3"&gt;A&lt;/div&gt;
          &lt;div class="col-md-6"&gt;
              &lt;div class="col-md-12"&gt;B1&lt;/div&gt;
              &lt;div class="col-md-12"&gt;
                  &lt;div class="col-md-8"&gt;B1.1&lt;/div&gt;
                  &lt;div class="col-md-4"&gt;B1.2&lt;/div&gt;
              &lt;/div&gt;
              &lt;div class="col-md-12"&gt;
                  &lt;div class="col-md-10"&gt;B2.1&lt;/div&gt;
                  &lt;div class="col-md-2"&gt;B2.2&lt;/div&gt;
              &lt;/div&gt;
          &lt;/div&gt;
          &lt;div class="col-md-3"&gt;C&lt;/div&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
