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".

However, using <del> for example to strike through text does not result in satisfactory output. Neither does using some other HTML tags like <strong> or <em>.

Admittedly, <strong> or <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?

  • @EightDaysofMalaise, since I didn't find information about this problem anywhere else, I thought of posting it here to get a definitive answer - maybe I'm the one doing something wrong. I admit, it grew into a bug/feature request the way I worded it at the end. The existence of 'features' and 'wish-list' tags confused me further into thinking this was OK (I now see what 'wish-list' tag is for). Should I remove it or just rephrase it (because I do see questions in the line of "is it possible" when it's clear the feature isn't there)? Commented Mar 2, 2012 at 8:23

    "Is it possible" entirely takes your question away from a feature request as other users can also say how or devs can come along later and say it's not possible. Commented Mar 3, 2012 at 1:03

    @DomDelimar consider editing your question to point to this answer as ~~ now supported in Trello.

While you still can't use tags (like <del>), in February 2014, Trello added the ability to cross out text using ~~foo~~.


Use double tildes to ~~strike~~ text in markdown!

    This works in some implementations of markdown, but not in Trello and not here on Stack Exchange.
