How does one hide text or pictures behind a spoiler tag?  I tried enclosing my post in square "spoiler" brackets--i.e. [spoiler][/spoiler]---but it didn't work, and I tried these brackets--<spoiler></spoiler>--but that didn't work, either.  What am I doing wrong here?

Not entirely sure if this will work:

 

Spoiler

I've tossed a spoiler button into the toolbar of the editor (between the quote and code buttons)

 

Legacy support for BBCode has been deprecated and disabled on these forums as a result.

I'll give it a shot.  Thank You.

What code does work now Simon? If I wanted to do a hero export for them.

None?  The forum-correct way to do it is through the use of multiple, nested containers with the various IPS-specific styles defined:

 

<div class="ipsSpoiler" data-ipsspoiler="">
	<div class="ipsSpoiler_header">
		<span>Spoiler</span>
	</div>

	<div class="ipsSpoiler_contents ipsClearfix">
		<p>
			hidden
		</p>
	</div>
</div>

 

So straight html with nothing special but the data tag. Got it, thank you.
