Today I wanted to include an extra log in a question, but felt it didn't need to take up vertical space when someone first looked at the question (the scrollbar on long code wasn't aggressive enough in my opinion), so I immediately reached for the <details> and <summary> tags, and was surprised to discover that they're stripped out.

Could these tags be supported? If not, what's the reasoning for not supporting them?

    I don't think so: my case isn't a snippet (it's a debug log that might be useful to someone who can diagnose nginx issues to more accurately answer what's going on) and <details> is already a standard HTML tag, not some new custom syntax.

    There are lots of html tags that are not supported, not just details which is pretty new. But this tag could be useful, if not used for something nefarious like hiding spam. Dec 18, 2021 at 21:42

    Actually hiding spam from casual view is one good reason why they may not adopt this. Dec 18, 2021 at 21:43
  • The details could just always be expanded in moderator view I think. The purpose of the tag would be to make it easier for answerers/questioners to read the post, not to substantially change the content. Though it may probably be a problem if what moderator initially sees differs from what users see, I dunno...

  • This is most definitely a useful feature that I would like to be added. It's not about "hiding spam". This is about providing all the needed context for a question, in a manner that enhances readability/overall view by allowing to hide memorizable information after a first read. E.g. you may need to provide a schema or json of some data; even with ad-hoc formatting and shortenings, the question may still end up being quite long and scary to review for potential answerers. An appropriate limitation in total characters for a question would still ensure that the <details> tag is not abused.
