Question

在构建我的网站时，我想添加一个使用 Javascript 进行动画处理的图像。我将 iFrame 与另一个 HTML 文档链接，然后一切正常，但我想将它循环进出。我在谷歌上搜索了它，但每个结果都带有 Youtube 嵌入的视频，谁能告诉我如何循环这个 iFrame。这是代码：

const banner = document.getElementsByClassName('banner')[0];
const blocks = document.getElementsByClassName('blocks');
for (var i = 1; i < 400; i++) {
  banner.innerHTML += "<div class='blocks'></div>";
  const duration = Math.random() * 5;
  blocks[i].style.animationDuration = 2 + duration + 's';
  blocks[i].style.animationDelay = duration + 's';
}

const section = document.querySelector('section');
setTimeout(function() {
  section.classList.add('active')
}, 13000); //14000 adds class active after 13s (13000ms)

@import url('https://fonts.googleapis/css?family=Poppins:400,500,600,700,800,900&display=swap');
* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
