<!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>
<title></title>
<style type="text/css">
p,ol,li {
  border: 1px solid black;
  padding-left: 10px;
  font-family: monospace;
  margin: 10px;
  margin-left: 0px;
}
ol {
  margin-left: 0px;
  padding-left: 40px;
  margin-top: 20px;
}
</style>
</head>
<body> 
<p class="my-class">p.my-class</p> 
<div id="my-id"> 
<ol> 
<li>div ol li</li> 
<li>div ol li</li> 
<li> 
<p class="my-class">div ol li p.my-class </p> 
</li> 
</ol> 
</div> 
</body> 
</html>

<!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>
<title></title>
<style type="text/css">
p,ol,li {
  border: 1px solid black;
  padding-left: 10px;
  font-family: monospace;
  margin: 10px;
  margin-left: 0px;
}
</style>
</head>
<body> 
<p class="my-class">p.my-class</p> 
<div id="my-id"> 
<ol> 
<li>div ol li</li> 
<li>div ol li</li>
