如何让瓶子看起来静止不动

Question

我创建了一个在 div 内带有标签的瓶子，随着 div 滚动瓶子和标签似乎在旋转，它会自动来回滚动。下面是一个演示以及 JSFiddle 中的代码。

如何让瓶子在 div 滚动和移动标签时看起来静止不动，这样瓶子看起来在页面中心来回旋转，而不是像往常一样向后移动标签确实如此。

Answer 1

K，大量编辑。 Fiddle: https://jsfiddle.net/pkfxqmLs/2/ 基本上我把它全部简化了...现在它的容器更简单了，它仍然允许你用鼠标滚动，但 RAF 循环也处理了它。远离背景图像，所有那些重复的段落元素等。不确定它是否仍然在视觉上 100% 是你想要的，或者你是否对所有不同的 p 标签做了一些缩短魔法......但是如果你希望你可以轻松地将它们添加回去并将它们定位为与当前的#bottle-label 元素完全一样。

滚动条的底部和遮罩的位置是固定的，推杆是空的div这样你就可以滚动整个东西。

HTML:

<div id="coke">

            <img id="bottle-mask" src="http://ipbyrne.github.io/bottle-demo/mask.svg" width="156" height="467"/>
            <img id="bottle-label" src="http://ipbyrne.github.io/bottle-demo/label.png"/>
            <img id="bottle-overlay" src="http://ipbyrne.github.io/bottle-demo/overlay.png" width="156" height="467" alt="Pure CSS Coke Can by Rom&aacute;n Cort&eacute;s" />
    <div id="pusher"></div>

    </div>

JS:

(function(){
          var number = 1
          var box=document.getElementById('coke');

          function infScroll(){
              box.scrollLeft   += number;

              if(box.scrollLeft===160){
                 number = number * -1;
              }

            if(box.scrollLeft === 0) {
              number = number * -1;
            }

            window.requestAnimationFrame(infScroll);

          }
          window.requestAnimationFrame(infScroll);
      }());

CSS:

正文 { 保证金：0；填充：0；高度：100%； }

#coke
{
    width: 156px;
    height: 500px;
    overflow: auto;
    position:relative;
}

#bottle-mask {
    position:fixed;
    left:0px;
    z-index:1;
}
#bottle-label {
    position: absolute;
    top: 140px;
    width: 325px;
    height: 250px;
    z-index: 2;
}
#bottle-overlay {
    position: fixed;
    left:0px;
    z-index: 3;
}
#pusher {
    width: 325px;
    height: 500px;
    position: relative;
    z-index: 4;
