Hello, I'm attempting to utilise CSS to add a background to my page. I'm attempting to reference an image that is in a different folder in a CSS file.
My CSS file:
#login-bg   
{
    background-image:url('/images/login/login_background.jpg');
    font-size: 20px;
}
My HTML code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<link rel="stylesheet" type="text/css" href="styles.css" />
</head>
<body id="login-bg"> 
<form action="" method="POST">
Username:  <input type="text" name="username" > 
<br>
Password:  <input type="text" name="password" > 
<br>
<input type="submit" value="enter"> 
</form>
</body>
</html>
Why I can't see my background image?
