default font size set in html or body tag in css?

[catfish]

After all these years I am back asking the proper method of specifying my font sizing in my css pages. Would this make sense to this..

html {
	height:100%;
	font-family: "Century Gothic", Arial, Helvetica, sans-serif;
}

body {
	margin: 0px;
	padding: 0;
	background-image: none;
	background-repeat:repeat;
	background-color: #000;
	font-family: "Century Gothic", Arial, Helvetica, sans-serif;
	color:#000;
	font-size: 62.5%;
}

#container{
	width:872px;
	margin:0 auto;
	background-color: #fff;
	border-right:3px solid #3160ac;
	border-left:3px solid #3160ac;
	font-size:1.4em;
}
h1 {
	margin: 0;
	font-family: "Papyrus", Arial, Helvetica, sans-serif;
	font-size: 2.75em;
	padding-top:20px;
	margin-bottom:6px;
	color:#3160ac;
	font-weight:bold;
}

This link I'm using % and em http://lambs.awardspace.com/index-two.php and this one I've used px http://lambs.awardspace.com/index.php Does anyone see any differance or problems with one or the other?
And I am also questioning using "Papyrus" (specified by the client but what would I use for the actual font-family here?

In Fx, I noticed a shift in menu text sizes, but body text sizes seemed to stay the same. As for the Papyrus font, any non-standard font that is not installed on users' computers would not be seen unless embedded on server. There are errors in HTML coding which should be corrected.

Personally, I would just use:

* { margin: 0; padding: 0; border: }

html, body { 
background: #000;
font-family: "Century Gothic", Arial, Helvetica, sans-serif;
color:#000;
font-size: 62.5%;
}

Set width/height in keeping with CSS rules. Might help:
