Only supporting users who have Javascript enabled
<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>
