Interesting ideas ~~ JS imitation WINXP logout desktop fade-out effect

Since I have seen a lot of people in the past, this kind of imitation XP is not very realistic, and I have come up with an idea in the past few days.

... Hey, it's funny.

Can you see it ~~ It should be okay ~~ HOHO ..

The general idea is that, no matter how long the entire document is, the scroll bar of the body disappears and the mask layer overwrites the visible area of the entire form!

The word "visible" is very important !!

Only the approximate effect is achieved. It is not very beautifying... haha. The remaining timeout makes the mask gradient. What should I do when I use it?

Below is the code

If it is good, add a score to bamboo. Hey, tks.Xmlns = "http://www.w3.org/1999/xhtml">
