Can anybody tell me how can i create this cool effect. 任何人都可以告诉我如何创造这种很酷的效果。 I know how to horizontally or vertically scroll the page using JQuery's localScroll.
我知道如何使用JQuery的localScroll水平或垂直滚动页面。 But if you have seen the webpage, look carefully how beautifully the lines run over the background.
但是,如果您已经看过该网页,请仔细查看线条在背景上的运行情况。 If anybody can tell me how is that effect created i will be very grateful :)
如果有人能告诉我这个效果是如何产生的,我将非常感激:)

[EDIT] [编辑]
It's not really an animation, but a little trick, based on the the transparency. 它不是真正的动画,而是基于透明度的小技巧。
Imagine the following HTML: 想象一下以下HTML:
<div class="div1">
<div class="div2">
</div>
</div>
div1 has the stripe-pattern background image, positioned as fixed, so it will move when you scroll. div1具有条纹图案背景图像,定位为固定,因此滚动时它将移动。
div2 has the partially-transparent background image, not fixed. div2具有部分透明的背景图像,而不是固定的。
So when you scroll the page, the pattern image will appear at some places, because the other background image is transparent, giving you a sort of animation effect. 因此,当您滚动页面时,图案图像将出现在某些位置,因为其他背景图像是透明的,从而为您提供一种动画效果。
