title: is the fist line comment css type declaraction still necessary?
body: <p>When I first started learning front end development I used to see the first line comment <br />
  /* css document */ 
  <br />
  or something to that extent, I can't remember what it was...<br /> 
  
  <li>I haven't used it recently. Is it even necessary anymore? </li>
  <li>Was that just a dreamweaver thing? </li>
  <li>Could having your first line of css as a comment be dangerous?</li></p>
