如何在jQuery中无限水平滚动图像？

Question

我试图将2个图像1叠加在另一个图像之上，并使用jQuery使它们无限滚动。 我可以使图像在CSS中滚动和分层，但是动画变得非常生涩。 如何使用jQuery在图像上创建无限水平滚动并保持动画流畅？

到目前为止，我的代码：

CSS：

@keyframes animatedBackground {
    from { background-position: 0 0; }
    to { background-position: 100% 0; }
}

#animate-area   { 
    width: 100vw; 
    height: 100vw; 
    background-image: url(http://oi64.tinypic.com/2r7ri29.jpg);
    background-position: 0px 0px;
    background-repeat: repeat-x;

    animation: animatedBackground 135s linear infinite;
}

#animate-area2  { 
    width: 100vw; 
    height: 100vw; 
    background-image: url(http://oi67.tinypic.com/2niy905.jpg);

    background-repeat: repeat-x;
  position: relative;
    animation: animatedBackground 80s linear infinite;
}

和HTML：

<div id="animate-area"></div>
<div id="animate-area2"></div>

基本上只使用了translate而不是background-position。

@keyframes animatedBackground {
 from { transform: translateX(0); }
 to { transform: translateX(100%); }
}

只需根据需要调整速度即可。

Answer 2

改变你的

@keyframes animatedBackground {
   from { background-position: 0 0; }
   to { background-position: 100% 0; }
}

至：

@keyframes animatedBackground {
   from { background-position: -100% 0; }
   to { background-position: 100% 0; }
}

片段：

 body { background-color: black; } @keyframes animatedBackground { from { background-position: -100% 0; } to { background-position: 100% 0; } } #animate-area { width: 100vw; height: 100vw; background-image: url(http://oi64.tinypic.com/2r7ri29.jpg); background-position: 0px 0px; background-repeat: repeat-x; position:absolute;z-index:-2; animation: animatedBackground 135s linear infinite; } #animate-area2 { width: 100vw; height: 100vw; background-image: url(http://oi67.tinypic.com/2niy905.jpg); position:absolute;z-index:-1; background-repeat: repeat-x; position: relative; animation: animatedBackground 80s linear infinite; } 

 <div id="animate-area"></div> <div id="animate-area2"></div>
