Hi philosopherdog, Welcome to the forum.
I've had a quick look at your webpage. The html seems fairly simple.
Here's a step-by-step which worked for me - I use the Firefox browser:-
- Open webpage. Right-click within the page and select 'Save Page As...' Point at your output directory and make sure to choose 'Save as type:Web page, complete' so that any images/stylesheets are also saved.
- Drag the saved html file into Calibre and edit metadata (Author, Title, Comments etc)
- Convert from ZIP to EPUB with your preferred settings in [Look & Feel].
In [Structure Detection] set 'Detect chapters at' to //h:h1
In [Table of Contents] set 'Level 1 TOC' to //h:h1
Then do the convert.
- View the resulting epub in the Calibre viewer and press the TOC button (7th from top in the sidebar). Voila - a nice single-level TOC down the left-hand side.
Please note that these settings are relevant for this particular web page as it uses <h1>...</h1> to mark its chapters. For a different webpage you would need to examine the html file to see how new chapters have been marked up.
Caveat - I have never owned or used an Apple device so I don't know whether there are extra special considerations.
Good luck
