title: Do you need to use Bootstrap's "container" and "row" if your content is to span the whole width?
body: <p>I think the standard of Bootstrap 3 and 4 is</p>
  
  <pre><code>&lt;div class="container"&gt;
      &lt;div class="row"&gt;
          &lt;div class="col-md-4"&gt; ... &lt;/div&gt;
          &lt;div class="col-md-8"&gt; ... &lt;/div&gt;   &lt;!-- just add up to 12 --&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>But what if you have a <code>div</code>, <code>table</code>, <code>form</code>, or any element, that you plan to just let it span the whole width?  Then do you need the <code>container</code> or <code>row</code> or <code>col-md-12</code> at all, for the whole page to display well under the styling rules of Bootstrap 3 and 4?</p>
  
  <p>P.S. if possible, please point to or quote the official Bootstrap docs related to this.</p>
