Auto Identifiers |
tags: headings, ids
A header without an explicitly specified identifier will be automatically assigned a unique identifier based on the header text. To derive the identifier from the header text,
- Remove all formatting, links, etc.
- Remove all footnotes.
- Remove all punctuation, except underscores, hyphens, and periods.
- Replace all spaces and newlines with hyphens.
- Convert all alphabetic characters to lowercase.
- Remove everything up to the first letter (identifiers may not begin with a number or punctuation mark).
- If nothing is left after this, use the identifier section.
Thus, for example,
| Header | Identifier |
|---|---|
| Header identifiers in HTML | header-identifiers-in-html |
*Dogs*?--in *my* house? |
dogs--in-my-house |
[HTML], [S5], or [RTF]? |
html-s5-or-rtf |
