I use Pandoc to convert a markdown table into a standalone HTML, but also
merge it with some HTML using the -B option. A recent update to MacOS Big
Sur causes pandoc to add additional, unwanted CSS information in the <head>
section that throws off the formatting, as well as this comment at the end.
<!--[if lt IE 9]>
<script
src="//cdnjs.cloudflare.com/ajax/libs/html5shiv/3.7.3/html5shiv-printshiv.min.js"></script>
<![endif]-->
This did not occur prior to the MacOS update, and this does not occur in a
Debian/Ubuntu based linux distribution. Only macOS Big Sur (so far that
I've found in my limited testing) seems to be affected.
Manually deleting the excess information in the head corrects the
formatting, but I cannot figure out a way to have pandoc not put it in
there. I've tried using the -B -H, but it keeps putting it in there above
my CSS formatting. I even tried changing my default browser in the OS
settings to see if that corrected it, since it seems like maybe its
detecting IE9? I dunno. Does anyone know how to fix? Been at this for a
couple of days now.
Thanks,
James

It has nothing to do with Big Sur. Most likely you've installed
a different version of pandoc than you were used to.
So, check the changelog
https://pandoc.org/releases.html
and you'll see an announcement of some changes to the default
CSS, as well as a way to disable it if you don't like it.
The html5shiv thing has always been there; it's a way to get
the HTML5 features to work with old IE versions, and it is just
a harmless comment otherwise. (At this point we could probably
remove it. IE 9 was released in 2011, and anyone using an older
version at this point should be very strongly advised not to!)

In an effort to make the answer more easily found for others who are also
asking the wrong questions, and looking in the wrong places. And also for
documentation purposes.
-M document-css=false
will stop pandoc from inserting CSS into the HTML header.
The long story..
An ansible script sneakily did a brew upgrade on a macOS dev machine just
prior to a big sur update. It upgraded pandoc (which had not been upgraded
in a while), then the OS got upgraded. After reboot, pandoc started
inserting CSS into the header that broke the styling. I tried to run
pandoc on a fresh install of linux mint with the latest updates and the *latest
version of pandoc* to troubleshoot. It didn't insert CSS into the header,
and the output styling was not affected. This further led me to believe
the OS update broke something. I Grabbed a new mac that also had the new
version of Big Sur, installed the latest version of pandoc, and it
generated lots of CSS that broke the styling.
So yes John, you're 100% correct that it had nothing to do with the Big Sur
update, and pandoc got upgraded. -M document-css=false proved that. Thank
you, I owe you a drink!
