jquery - 垂直居中对齐全屏 div

Question

其实我想做一个全屏的div，div里面的文字会垂直居中。我通过 css 尝试了很多，但没有完全按照我的意愿工作。我知道如果我修复了 div 它会起作用，但我也想向下滚动到另一个 div。

我希望我的元素看起来像(初始全屏部分):http://perfectpointdev.com/perfect-design/

我想把我元素的灰色背景部分作为perfectpointdev.com网站的初始部分。请帮帮我...

我在 jsfiddle 中的演示元素:http://jsfiddle.net/zinannadeem/08wve09t/
