title: How to use css first-child with :not()
body: <p>There is a parent <code>div</code> with <code>id = "cooldiv"</code>. It has many <code>div</code> elements inside. Now I need to set a css property to all the child <code>div</code>-s except the first one.</p>
  
  <p>So, this is what I've tried so far to accomplish this task:</p>
  
  <pre><code>#cooldiv .row:not(first-child) {
      top: -50px;
  }
  </code></pre>
  
  <p>But, of course, it didn't work out. What's wrong here? This is the screenshot of the source code:</p>
