title: How to change two Div placement via CSS
body: <p>I have a <code>html code</code></p>
  
  <pre><code>&lt;div class="main"&gt;
    &lt;div class="child1"&gt;I'm working Child 1&lt;/div&gt;
    &lt;div class="child2" &gt;I'm working Child 2&lt;/div&gt;
    &lt;div class="child3" &gt;I'm working Child 3&lt;/div&gt;
  &lt;/div&gt;
  &lt;div class="another"&gt;
   &lt;div class="child111"&gt;I'm working Child 111&lt;/div&gt;
  &lt;/div&gt;
