This is a confusing statement. If you want to generate the output with a
cgi program, the cgi program has to generate *all* of the output.
Having the cgi program generate all of the output, and having it use your
style sheet can resolve your problem.

Did you perhaps use 'div class='leftcolumn' ?
That will not work with your stylesheet.
div id='leftcolumn' *will* work
Here is a little cgi program that uses CGI.pm and your style sheet to print
a some stuff in a blue column on the left side of the screen:
#!/usr/bin/perl
use warnings;
use strict;
use CGI;
my $q = CGI->new();
print $q->header(), $q->start_html(-title=>"list msg test",
-style=>{'src'=>'/css/se.css'}),
'';
for (my $i = 1; $i < 26; $i++) {
print $q->br("blue column line $i");
}
print '', $q->end_html();

You seem to be under the mistaken impression that you cannot get input using
CGI.pm or Template::Toolkit.
That is incorrect, either of those tools allow you to generate forms that
can be used to get input from the user.
If you look at perldoc CGI the very first screen contains an example of how
to generate a form.
Hope this helps,

I have tried that and when I tried to call up a div object, in my css
(is attached) called leftcolumn, instead of getting a navy blue column
on the left side of the page it is just white.

- From what I see in the tutorial,
http://template-toolkit.org/docs/tutorial/Web.html#section_Dynamic_Content_Generation_Via_CGI_Script,
the Templete Toolkit only outputs information from the script, but I
need it to handle input as well, my script I am working on is a
guestbook so it needs to get the name of the guest and a message then
output it, as well as save it to a log for later use by the script.
Everything works but the plain white background is ugly and doesn't
match the rest of my site which is why I started this thread.

You could then just take your regular html page with your css stuff applied and replace those bits that have to have a calculation or other function with a template var. you then can maintain the look of your static pages with your dynamically generated pages .

I've going to cover some basics here, so I apologise if its starting too low for you. When a browser requests a URI, the server gets the content of that URI from somewhere and sends it back. It might get it from a file, it might get it from somewhere else. In the case of CGI, it runs a program and returns that instead. You need to edit the Perl program that is being called using CGI so it outputs the HTML that you want. (Including the to the stylesheet you are using, there is no problem with support for CSS, since when is output is just HTML, that is comes from a program rather than a file isn't relevant). We've no idea what method the program is currently using to determine what HTML is generated, so we can't tell you what needs to be done to edit it. What we can tell you is that using Template-Toolkit is a good approach when it comes to writing this kind of system. When using TT the general approach is to: (1) Gather up all the data you want into a Perl hash (2) Tell TT to process a template using that data TT then goes over the template (which might look something like: http://github.com/dorward/axford/tree/master/root/default.tt (sorry, its got a lot of legacy cruft in it, I'm in the process of cleaning it up) and replaces placeholders with the data (and has things to loop over arrays when you have repeated data). -- David Dorward http://dorward.me.uk/ -- To unsubscribe, e-mail: beginners-cgi-unsubscr...@perl.org For additional commands, e-mail: beginners-cgi-h...@perl.org http://learn.perl.org/

Are you using CGI.pm?
If so, you can use css by adding: -style=>{'src'=>'/mystyle.css'} to
the aguments of start_html:
print $q->start_html(-style=>{'src'=>'/mystyle.css'});
This will cause your cgi code to use the stylesheet.
If you are not using CGI.pm please specify what other module(s) you
are using, or if you are just generating the html yourself (not
recommended).
If you are generating the html directly in your perl code, you can
insert a stylesheet reference between the and tags just
as you do in a plain html page.
Template toolkit is a very useful and powerful tool, but it is
probably overkill if all you want to do is use stylesheets. You can
do lots of other things with Template::Toolkit that may make it worth
the time is takes to learn how to use it. For example, having header
and footer information that appears on all of the pages on your site
in a template, allowing you to make one change to the template and
have that effect your entire site. You can also use template toolkit
to generate static pages, so you can use templates to generate pages
that do not require cgi, and re-used those templates in you cgi
scripts.

Unfortunately, you'll probably just have to work through some of the examples to see how it helps you. As with much of perl, there are many ways to do it. I think, though, that many folks have thought about the problem of producing HTML from perl scripts and found that templating is the way to go. Also, you might want to look at a solution like CGI::Application that does much of the busy-work of writing CGI applications for you and enforces the MVC concept by design.

Have a look at: http://template-toolkit.org/ The goal of using a "template language" is to remove all those ugly print statements from your code. Instead, you use the template system to write HTML with a few extra tags in it that can use data that is passed into it to dynamically change parts of it. The main idea, though, is to separate your code (the part that does the database calls, validation, etc.) from the display of the results; the two are nearly orthogonal concerns.
