SPOILER ALERT! - A jQuery Plugin Which Uses Blurs For Hiding Spoilers

SPOILER ALERT! is a jQuery plugin which uses blurs to hide spoilers from readers online. However, SPOILER ALERT!  adds some more bells and whistles to the concept by enabling you to specify maximum blurs and partial blurs.

Maximum blur is used to hide the spoilers completely from the readers. However, upon hover, the partial blurs are applied which makes the content a bit more distinguishable. Finally, clicking upon the blurred content fully reveals the hidden material.

SPOILER ALERT! can not only be used for blurring out spoiler texts, but can also be used for images. This technique for hiding spoilers is a nice change from the usual blacked out or completely hidden text we usually find on website as it keeps the flow of the content essentially the same.
