Host-sensitive style sheet

#1

I have a pair of webservers (actually virtual hosts in the same apache).
They are mostly clones, but one is used to develop changes, so is the
test system.

Most of the pages are generated by CGI scripts, and on the test system
the header incorporates <BODY BGCOLOR=#FFD0D0> generating a puce
background which warns people of the test environment.

I can easily change this to inline CSS, but I'd prefer to use an
external stylesheet. I could use different stylesheets for the test and
production systems (and probably will, so I can test the effects of
changes in the stylesheet itself) but I started to wonder if there were
any way within CSS of setting the background colour based on the host.

One great advantage of a stylesheet which is sensitive to the host is
that it would solve the problem of having static HTML pages which
changed their background colour based on which host was being used.

No. But you can create segregate the difference off into a separate pair
of files named, say, bodybg.css, one on the test server containing only

body { background-color: #ffd0d0; }

and one on the production server containing only

body { background-color: #ffffff; }

Then, in your main CSS file, remove the rule that sets the background
color, and include

@import "bodybg.css";

at the top.

Perl:

use CGI;

sub localMode
{
$localServerName=shift;
if( $ENV{SERVER_NAME} eq !localServerName)
{
return(
style({-type=>'text/css'},'body { background-color: #ffd0d0; }')
);
}
else
{
return('');
}
}

PHP

function localMode($localServerName)
{
if($_SERVER['SERVER_NAME' == $localServerName)
{
return '<style type="text/css">body { background-color:
#ffd0d0;</style>';
}
else
return '';
}
}

Just place function AFTER the last STYLE link.
