Trello accepts Markdown in card descriptions and it even helpfully links to the Markdown syntax page.
That page mentions that "for any markup that is not covered by Markdown’s syntax, you simply use HTML itself".
<del> for example to strike through text does not result in satisfactory output. Neither does using some other HTML tags like
<em> really don't have to work because Markdown supports bold and italic formatting, however Markdown unfortunately lacks in
<del> department, and probably in others too.
Is there a way to show that a text previously existed but now does not, in Trello, if strikethrough is not available?
~~now supported in Trello.
