title: What are the concerns of usability or accessibility on using a custom scrollbar in a webpage?
body: <p>Posted this question a while back but it got close as opinion-based? I now have an answer.</p>
  
  <p>What are the benefits to customize scrollbar for a webpage in relation to user experience?</p>
  
  <p>Would if affect the user experience badly in any way? if Yes how ?</p>
  
  <p>Is there any relation between custom scrollbar in relation to the site content and user age ? For example, cartoons game sites can have custom scrollbar to reflect the site content in a positive way</p>
