You may already be aware that it is possible to prod CGI into emitting a reference to an external style sheet. For that you have to do the following...

  use CGI qw/Link/;

... because the Link method is not exported by default. Once you have done this you can then say: 

  print $q->start_html({
    -head=>Link({-rel=>'stylesheet', -type=>'text/css', -href=>'/foo.c
+ss'}),
  });

And when you look at the HTML you'll see something like <link type="text/css" rel="stylesheet" href="/foo.css" />. I ran into the situation today where I had to include two stylesheets, and the following didn't work: 

  print $q->start_html({
    -head=>Link([
      {-rel=>'stylesheet', -type=>'text/css', -href=>'/foo.css'},
      {-rel=>'stylesheet', -type=>'text/css', -href=>'/bar.css'},
    ]),
  });

That is, the transitive array reference [ ] trick doesn't work for the Link method. After trying a couple of things out, it turns out that a brute force method below works fine.

This node is dedicated to wil. :)

  print $q->start_html({
      -head=>Link({-rel=>'stylesheet', -type=>'text/css', -href=>'/foo
+.css'})
        . Link({-rel=>'stylesheet', -type=>'text/css', -href=>'/bar.cs
+s'}),
    });
