HTML Authoring Pitfalls

If you view

/tuning/topicId_31242.html#31242

you will see the result of coloring all horizontal lines white in HTML (which is not carried over in the text-based source document, with direct link below:

/tuning/topicId_31242.html#31242?source=1

yielding the (text) source document.

That the color information is (not surprizingly) not retained in the source document, the (to me) less obvious detail is the grotesque results of some of my (HTML) "touch-up" work. So, I'm gonna forget about letting HTML "fix" my diagrams with such "window-dressing" code, leaving the source all fubarred...
