Which publishing service has a spoiler in the design?

Question

Text editors

I want to publish a summary of an article of a gigantic volume for the general public, but in such a way as not to cut out pieces, but hide them under a spoiler. I would use telegraph or teletype, but there, to my surprise, there is no spoiler. Do not post in LiveJournal, in fact. What would you advise, which platform?
