I stumbled into this site, it really looks simple and I want to imitate it but I am not knowledgeable enough with website design so I am asking for your help guys. Perhaps my 1st question is: regarding the underline, is that a HR? How do I place it in a margin?

Thanks for any help with my stupid questions. Just want to explore things.

I've got this starting code in case you are interested:
Code:
<html>
<head>
	<title>testing</title>
</head>

<body>
	<p style="font-family:verdana;font-size:4em;margin: 1cm 1cm 1cm 1cm; ">this is my name</p>
	<hr />	
</body>
</html>
