I have a web page (below) with embedded PHP that sets a $months variable
and then calls remind -p and sends the output into rem2html.

rem2html is from /usr/share/doc/remind/examples/www/rem2html.gz
See Also /usr/share/doc/remind/examples/www/README.rem2html

rem-default.css is from /usr/share/doc/remind/examples/www/rem-default.css
with my own customization styles added for my web reminders.  I have
added a lot of custom styles for reminders in the calendar that I use
with class= attributes in "SPECIAL HTML" lines like this:

PUSH-OMIT-CONTEXT
    OMIT Jul 11 2021
    FSET t() _StartT(120) + " iOpener Dance "
    set d "++99 AT 10:00 SUN SKIP"
    REM [d] MSG %"%"[t()] [_End()]%
    REM [d] SPECIAL HTML <a class="ian-dance" href="http://www.iopenerdance.com"
>[t()]</a>
POP-OMIT-CONTEXT

I have _Start() and _End() functions that mess with how the date/time
is displayed depending on how far into the future the reminder is.

This page below needs the latest remind from git to use the -u+ and -+ options.
