I would expect the table of contents to only have: + + * Heading 1 + * Subheading 1 + * Heading 2 + +... and somehow ignore my title. + +That is hard to fix without changing the theme significantly. ikiwiki themes frequently workaround that problem by showing the title using another markup element, generally a ``. But I find that confusing as well, because `` is a generic, non-semantic element, which, even worse, is by default not a "block" like a heading. In bootstrap, for example, you would need to copy all the logic surrounding headings to a theme customization to make it work, but that leads to a lot of CSS duplication. + +There should really be a way to skip those entries. The patch mentioned here does this by doing a tiny modification to `toc.pm` to skip headings with the magic `nocount` class. The naming comes from [Phil Archer's Automatic Heading Numbering CSS hack](https://philarcher.org/diary/2013/headingnumbers) and could be changed, but it seemed logical to me. The result can be seen in action in: . + +Thank you for your consideration.
