title: Should I always nest selectors in other selectors when using sass?
body: <p>My question is about nesting in sass or scss. It is a good thing from the readability perspective that we can nest selectors inside another selectors in sass but is it something that we must do? I am a little bit confused because when I run scss-lint, then I'm getting some errors nesting depth. I red a few articles and now I know that we should go deeper than nesting more than 3 rules one inside another. </p>
  
  <p>So I have two questions:</p>
  
  <ol>
  <li><p>Is there anything wrong if I will write my rules in sass just like this (without nesting):</p>
  
  <p>.my-class
      ...</p></li>
  </ol>
  
  <p>Instead of writing like that: </p>
  
  <pre><code>header
      nav
          .myclass
  </code></pre>
  
  <ol start="2">
  <li>Can you explain why is it necessary to nest in sass and what are the advantages of nesting? I know that it is good for overriding rules, but if I don't need to nest that deep? I will appreciate any answers or even links to some articles explaining my questions in more detail. </li>
  </ol>
