How to spoiler something

[LSLGuy]

Even more about spoilers:

Nested spoilers?

I found an old thread that I’d posted in a few years back - in which I had posted something with two or perhaps 3 levels of spoilers. You can click on the blurred bit - which displays the outermost spoiler, Then a grayed bit showing the next level - but clicking on that just hides the whole thing again. Fixable?
