Template:Spoiler

This will let you black-bar some text in an article, so that people who are reading it casually won't read something that will "spoil" a surprise in the associated story. If you want to see what's there, you gotta highlight by clicking the cursor and dragging it over the black bar.

Do not confused this with with the tag-template Template:Spoilers; that's for when the whole damn article is a spoiler, or there's so many spoilers that the article would look like a zebra's birth-defect.

It's supposed to have mouse rollover for changing text, so you don't have to drag the mouse. Dunno why it's not working.

Usage:

''Spoiler:''{{Spoiler|Snape kills Dumbledore}}

Spoiler:Snape kills Dumbledore
