title: It faster to style an element through a class or starting with a parent CSS/HTML
body: <p>I am sorry if my question is not overly clear.</p>
  
  <p>I will first illustrate my question with an exmaple:</p>
  
  <pre><code>&lt;div id="parent"&gt;
    /*This contains a dynamically generated amount of children from 1 - 200*/
    &lt;div class="child"&gt;&lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Is it best practice/faster to style each child using <code>.child {}</code> or using <code>#parent div {}</code></p>
  
  <p>If there are 200 children then that is a lot of additional text.</p>
  
  <p>Thank you</p>
