Spoilers 介绍
Spoilers implements an idea first seen on imdb.com, where it is used to hide
“spoiler” text from casual readers who may not want to know too many details
about a film before seeing it. (An example of a “spoiler”, in that context,
would be revealing the identity of the culprit in a crime film.) This plugin
hides “spoiler” text behind a graphic until the user mouses over the graphic,
at which point the text is revealed.
