Basic HTML tags¶
A main focus of the Fediverse is microblogging, using objects
of type Note to represent posts. This support table shows a set of tags, that
we consider reasonable to support for such a purpose.
The ✅ means that the html tag was left unchanged. ❓ indicates the content was changed, by hovering over it, one can see into what.
❓ for misskey is due us not supporting checking markdown yet.
