On a shared host where you have a cgi-bin directory, start off with a simple script. It doesn't even need to be Perl - it could be anything that prints to STDOUT and is executable.
The minimal response from any of these programs is this,
Status: 200
Content-type: text/html
<!doctype html>
<html> HTML Goes Here </html>
See https://www.perl.com/article/perl-and-cgi/. I also recommend checking out CGI::Tiny. If you're on a shared host that's "powered" by cPanel/WHM, then you can likely install Perl modules locally via the cPanel interface (ask your host if you don't know). There's also cpanm coupled with local::lib.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
