I have a Web page here: Dima Dayoub and have tried to add a log-in button to it. The log-in button has this code (stripped down for ease of reading):

<link rel="stylesheet" href="css/style2.css" />

<style type="text/css">

.list-inline {
  list-style: none;

.list-inline > li {
  display: inline-block;



        <div id="container">
              <div id="loginContainer">
                <div style="clear:both"></div>
                <div id="loginBox">                
<form id="loginForm" method="post" action="submit1.asp">

<fieldset id="body">
<label for="UserID">Username</label>
<input type="text" name="UserID" id="UserID" /></fieldset>
<label for="Password">Password</label>
<input type="Password" name="Password" id="Password" />

<input type="submit" name="Login" id="Login" value="Login" />


<div id="main">	
<div id="site_content">
<div id="site_heading">
<div id="logo">
<div id="logo_text0">

<h1>dima <span class="logo_colour">dayoub</span></h1>

<ul class="list-inline">
<li><img id="picright1" src="images/facebook.png" width="64" height="64" alt="Facebook" /></li>
<li><img id="picright2" src="images/twitter.png" width="56" height="56" alt="Twitter" /></li>
<li><img id="picright3" src="images/rss.png" width="56" height="56" alt="Rss" /></li>
<li><a id="loginButton"><span>Login</span></a></li>

The new page that includes the log-in button is here: Dima Dayoub but my background image (background.png and shown in the stylesheet for index.asp as style.css) has vanished.

How would I bring it back, please?
