I am using org-mode publishing to generate html files from org files.
The attached example mostly works.
The resulting html file is published at https://wolf-test.netlify.com/f1.html
I am using Emacs 26.1 with Evil Spacemacs 0.200.13 and org-mode version 1.9.1 

I have the following questions about Org publishing:
1)
Org publishing generates unused JavaScript functions:

line 42 CodeHighlightOn(elem, id)
line 52 CodeHighlightOff(elem, id)

Is there a way to publish the pages without generating any JavaScript?

2)
Org publishing generates a page title which looks like this:

<title>&lrm;</title>

How to make it like this?:

<title>file name</title>


3)
Various org-publishing options are listed in org-mode manual "13.1.5 Options for the exporters" .
What are the left and right columns for?
Where is the documentation that explains how to use the options?
For example, "title" is listed but I can't figure out how to use them:


‘:with-title’             ‘org-export-with-title’


org-export-with-title is in the Emacs help as a variable but it doesn't say how to use it.
