title: Only supporting users who have Javascript enabled
body: <p>I am considering creating a website that only supports users with JavaScript enabled.</p>
  
  <p>My justification for this is that I want to offer a rich user experience, in a fairly limited time budget, so if I only support people who have JS enabled, I don't have to spend time making sure the UI works without JS and create server side equivalents for validation etc.</p>
  
  <ol>
  <li>Is this possible? Do different browsers\platforms prevent me from achieving this?</li>
  <li>What percentage of users have JS disabled these days?</li>
  <li>How would I go about checking if JS is enabled in C#.</li>
  </ol>
