html - Css循环动画

Question

我的动画有问题，单词应该重复“n”次

上面提到的代码有 9 个不同的单词，一个接一个地有一个淡入淡出的动画，但是这个动画只有一次。我需要的是循环使用相同的动画一次又一次地迭代，当最后一个单词结束时，第一个单词应该被加载。

这是 html/css 代码:

    h1.main,p.demos {
    	-webkit-animation-delay: 18s;
    	-moz-animation-delay: 18s;
    	-ms-animation-delay: 18s;
    	animation-delay: 18s;
    }
    .sp-container {

我不太理解你的代码，但你可以做的是为每个元素创建一个动画，并为动画的每个元素定义相同的持续时间(总动画时间)。之后，您只需使用 %

处理“显示的内容”

在我的示例中，我将处理 4 个元素，因此每个元素占总时间的 25%(fadeIn fadeOut 占 +/-5%)

.el-1, .el-2, .el-3, .el-4 {
  position: absolute;
  width: 100px;
  height: 100px;
  animation-duration: 10s; /* Total time */
  animation-iteration-count: infinite;
  animation-delay: 0; /* by default */     
}
.el-1 {
  animation-name: example-1;
  background: red;
}
.el-2 {
  animation-name: example-2;
  background: green;
}
.el-3 {
  animation-name: example-3;
  background: blue;
}
.el-4 {
  animation-name: example-4;
  background: yellow;
}


@keyframes example-1 {
    0%   {opacity: 0;}
    5%   {opacity: 1;}
    20%  {opacity: 1;}
    30%  {opacity: 0;}
    100% {opacity: 0;}
}
@keyframes example-2 {
    0%   {opacity: 0;}
    20%  {opacity: 0;}
    30%  {opacity: 1;}
    40%  {opacity: 1;}
    60%  {opacity: 0;}
    100% {opacity: 0;}
}
@keyframes example-3 {
    0%   {opacity: 0;}
    40%  {opacity: 0;}
    60%  {opacity: 1;}
    70%  {opacity: 1;}
    80%  {opacity: 0;}
    100% {opacity: 0;}
}
@keyframes example-4 {
    0%   {opacity: 0;}
    70%  {opacity: 0;}
    80%  {opacity: 1;}
    95%  {opacity: 1;}
    100% {opacity: 0;}
}

<div class="el-1">1</div>
<div class="el-2">2</div>
<div class="el-3">3</div>
<div class="el-4">4</div>
