CSS: Spoiler + Color tag

[Hares]

If you have

color

tag within your spoilered text, like this one, then you are able to see its contents even before spoiling.

This also affects

spoilers

within the color tag.

A side note

Note that this (obviously) affects only unparameterized (non-collapsible) spoiler tag.

Also, double spoiler is a real thing.

P.S.
Single or double linebreak after closing spoiler tag is ignored. But triple is not!
