Cufon line-height problem

Question

When I apply line-height in CSS or in javascript, it does not do it. And if I apply in the script, I get the following error.

Error: missing : after property id
Line: 26, Column: 44
Source Code:
Cufon.replace('#header .lists li a', {line-height: '120%;', font-size: '120%'}); 

javascript

$(document).ready(function() 
{

    Cufon.replace('#header .lists li a', {line-height: '120%;', font-size: '120%'});

});

style.css

#header .lists { float:left; position:relative; width:776px; height:40px; list-style:none; padding:0; margin:0; margin-top:1px; background:url(../images/bg_mainmenu_off.gif); z-index:100; }
#header .lists li {float:left; height:40px; display:inline; background:url(../images/bg_mainmenu_off.gif) repeat-x;}
#header .lists li a {display:block; width:150px; height:40px; line-height:40px; text-decoration:none; font-size:16px; font-weight:bold; text-indent:10px; font-weight:bold; color:#FFFFFF; margin: 0px; }
#header .lists li a:hover { background:url(../images/bg_mainmenu_on.gif) repeat-x; }
#header .lists div {display:none; }
#header .lists :hover div {display:block; position:absolute; background:#FFFFFF; top:26px; border:1px solid #ece7d1; padding-bottom:10px;}
#header .lists :hover div dl { float:left; width:179px; display:inline; padding:5px; margin:0 5px 10px 5px;}
#header .lists :hover div dl dt { width:179px; height:16px; background:#b39f87; margin:5px 0 10px 0; text-decoration:none; }
#header .lists :hover div dl dd {padding:0; margin:0;}
#header .lists :hover div dt a { display:block; height:14px; line-height:14px; font-size:14px; color:#FFFFFF; font-weight:bold; text-decoration:none;}
#header .lists :hover div dt a:hover { background:none;}
#header .lists :hover div dd a { display:block; height:14px; line-height:14px; font-size:14px; color:#b39f87; font-weight:normal; text-decoration:none; }
#header .lists :hover div dd a:hover {text-decoration:underline; background:none;}

Answer 1

There is a known bug in Cufon that will probably not be fixed regarding flaky line-height recognition on pages with non-strict doctypes.

Answer 2

Also the following CSS styling worked for me without Doctype change (like the post from Keith before)

div#navigation ul li cufon {
    padding-bottom: 3px;
}
