The <body> of my node.js client is missing

This is the client html:

<!DOCTYPE html>
<html xmlns="" xml:lang="en" lang="en">
	<title>All Fours</title>
	<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
	<!--<link href="/common/default.css" rel="stylesheet" type="text/css" />-->
	<link href="cards.css" rel="stylesheet" type="text/css" />
	<style type="text/css">

	.cardArea {
	  font-size: 20pt;
	  float: left;
	  margin-right: 1em;
	  position: relative;
	  width:  4.50em;
	  height: 5.00em;
	<script type="text/javascript" src=""></script>
	<Script src="/"</script>

<div id="demoBox">

<h2>All Fours</h2>

<button onclick="shuffle()">Shuffle Deck</button>
<button onclick="var hand = deal(6)">Deal</button>
<button onclick="discard()">Discard</button>
<button onclick="reset()">Reset Deck</button>


<div id="table">
  <div id="deck"     class="cardArea"></div>
  <div id="hand"     class="cardArea" style="width:10em;"></div>


It looks like something messed up and only a small section of your code was posted. You will need to fix this before anyone will be able to help.

I cleaned up your code.
You need to use triple backticks to post code to the forum.
See this post for details.
