Question

在我的网站中，我想创建一个CSS动画，在该动画中，我试图在延迟1秒后一个接一个地翻转多个图像，但是它不起作用。当第一张图像翻转时，第二张图像应翻转然后再翻转，依此类推

像this一样，但是在载入时，每个图像都应该一个接一个地翻转。假设有4张图片，第一张图片的延迟为0，然后第二张图片的延迟为：1，依此类推，直到第四张图片的延迟为：4

javascript

document.addEventListener("DOMContentLoaded", function() {
    var rotateComplete = function() {
    with(target.style) {
      webkitAnimationName = MozAnimationName = msAnimationName = "";
    }
    target.appendChild(arr[0]);
    setTimeout(function(el) {
      with(el.style) {
        webkitAnimationName = MozAnimationName = msAnimationName = "rotator2";
      }
    }, 0, target);
  };

  var target = document.getElementById("rotator2");
  var arr = target.getElementsByTagName("a");

  target.addEventListener("webkitAnimationEnd", rotateComplete, false);
  target.addEventListener("animationend", rotateComplete, false);
  target.addEventListener("MSAnimationEnd", rotateComplete, false);

}, false);

第一张图片在不断翻转

Answer 1

如我所说，如果我对您的理解正确，则可以使用animation-delay。该值为

（卡索引）* animation-duration。

更新

要使其无限运行，动画应采用不同的计算方式，因为它应注意后面的动画。

计算是

0.3s（翻转动画）* 5（4张卡+迭代之间的延迟增加1张）* 2（来回）= 3s。

因此，每个“刻度”为10％。我们想在动画的中间将其翻转回50％。后面的动画刻度增加10％。

这是生命周期：

|---|---|---|---|---|---|---|---|---|---|

|___|___|___|___|___|___|___|___|___|___|
Front w   w   w   w  Back w   w   w   w
 .3s .3s .3s .3s .3s .3s .3s .3s .3s .3s 
|_______________________________________|
                   3s

延迟一段时间后，一个接一个的翻转多个图像
