CSS动画对所有动画重复

Question

我有一个文字动画如下。但我不能将动画-迭代-计数应用于整个过程。我需要从一开始就重复所有的动画。从第一帧到第五帧，谢谢

HTML：

<div class="sp-container">
        <div class="sp-content">

                <h2 class="frame-1">It's destroying the planet</h2>

                <h2 class="frame-2">It's mass, mechanized murder</h2>

                <h2 class="frame-3">You can stop it</h2>

                <h2 class="frame-4">Now!</h2>

                <h2 class="frame-5"><span>Save the planet.</span> <span>Love life.</span> <span>Go vegan.</span></h2>


        </div>
    </div>

CSS：.

sp-container {
  position:relative;

Answer 1

您应该使用JS脚本，如下所示

<script>
  // setting the element
  element = document.getElementById("ad");
  // reset animation
  setInterval(function() {
    // -> delete class
    element.classList.remove("animation");
    // -> triggering reflow /* The actual magic */
    // without this it wouldn't work. Try uncommenting the line and the transition won't be retriggered.
    element.offsetWidth = element.offsetWidth;
    // -> add the animation class so the animation is restarted
    element.classList.add("animation");
  }, 7000);
  // this is the timmer which sums up the total of animation time of elements and delays calculated by you

</script>

如果ad元素是您的父元素，并且所有动画都是在.ad.animation .element{//animation defined here}的类下定义的，那么主元素应该已经开始了，定义如下：

<div onclick='window.location.href="http://www.google.com"' id="ad" class="ad animation"> 

在这里，您可以更改链接到任何您想要的(自定义或googleAds/其他广告提供商)，并立即启动动画。7000毫秒表示动画的总时间，相应地更改它。希望这对你有帮助，并能帮助你。
