I posted this question on another list and received a response consisting of
potentially helpful code. It has not been tested on my end, but I thought
I'd pass the information along.
Share the wealth.

Assuming you want to go ahead and do multiple style sheets:
One idea is to head on over to a big site which does this (i think cnn.com
does, but i only say that because i always see Netscape-specific banners
and such) and grab the different style sheets (by browsing it with
different browsers or changing the id of your browser, as Opera and
Konqueror allow for). i work for an internet company and can say that
Netscape gives our web designers no end of grief, and it's about impossible
to make something look good in Netscape 4.x.
Below are some functions which might help you in determining which style
sheet you want to show. Using those it becomes a simple matter of including
a style sheet named r_get_browser_name().".css".
function r_get_browser_name() {
/* Get the Browser data */
$browsers = array();
$browsers['MSIE'] = "!MSIE!";
$browsers['Konqueror'] = "!Konqueror!";
$browsers['Lynx'] = "!Lynx!";
$browsers['Opera'] = "!Opera!";
$browsers['WebTV'] = "!WebTV!";
$browsers['Bot'] = "/bot|Slurp|Infoseek|Spider|Google/";
$browsers['Netscape'] = ",(Mozilla\/4|Nav|Gold|Netscape),";
$browsers['Mozilla'] = "!Mozilla!";
$browser = "Other";
$agent = r_find_var( 'HTTP_USER_AGENT' );
# echo "agent=[$agent]<br>";
while( list($k,$v) = each( $browsers ) ) {
if( ! preg_match( $v, $agent ) ) continue;
$browser = $k;
# r_debug_log( basename(__FILE__),__LINE__,": [$browser]: regex = $v.
Agent=[$agent]" );
#echo "browser match: browser=[$browser]: ";
#echo "v=$v<br>k=$k<br>";
break;
}
#echo "<b>browser=[$browser]</b><br>";
return $browser;
}
function r_get_browser_os() {
/* Get the Operating System data */
$oses = array();
$oses['Windows'] = "!Win!";
$oses["OS/2"] = "!OS/2!";
$oses['Mac'] = "!Mac|PPC!";
$oses['Linux'] = "!Linux!";
$oses['FreeBSD'] = "!FreeBSD!";
$oses['SunOS'] = "!SunOS!";
$oses['IRIX'] = "!IRIX!";
$oses['BeOS'] = "!BeOS!";
$oses['AIX'] = "!AIX!";
$os = "Other";
$agent = r_find_var( 'HTTP_USER_AGENT' );
while( list($k,$v) = each( $oses ) ) {
if( ! preg_match( $v, $agent ) ) continue;
$os = $k;
#echo "agent=[$agent]<br>OS match: OS=[$os]: key=[$k] pattern=[$v]<br>";
break;
}
#echo "<b>OS=[$os]</b><br>";
return $os;
}
function &r_find_var( $var, $defaultval = null ) {
foreach( array(
$GLOBALS,
$GLOBALS['HTTP_POST_VARS'],
$GLOBALS['HTTP_GET_VARS'],
$GLOBALS['HTTP_SERVER_VARS'],
$GLOBALS['HTTP_COOKIE_VARS']
)
as $ar ) {
if( isset( $ar[$var] ) ) return $ar[$var];
}
return $defaultval;
}
