Please review a reasonably simple, mostly doc-only change to reorder and
document some groups of members of HtmlStyle.
The change is primarily to document members in the conceptual groups
regarding member signatures, flex layout, and descriptions/notes. Other
potential groups will be identified and done separately.
The only code change is to rename `arguments` to `parameters`, in
accordance with standard usage. This requires a corresponding change in
the style sheet, and some updates to tests. The test updates were all
done automagically.
