There is no specific handling of indented headings (or anything else) in markdown. While it is possible to use an indent to headings on their text:
# Mercury
## Venus
### Earth
#### Mars
…such style is uncommon, a bit hard to maintain, and it’s impossible to add a heading with a rank of 5 as it would form indented code instead. So it’s recommended to not indent headings and to turn this rule on.
remark-stringify
formats headings without indent.

Projects maintained by the unified collective are compatible with maintained versions of Node.js.
When we cut a new major release, we drop support for unmaintained versions of
Node.
This means we try to keep the current release line,
remark-lint-no-heading-indent@5
,
compatible with Node.js 16.
