如何显示前三个徽标等待几秒钟并无限循环显示接下来的三个徽标？

Question

我现在有 9 个徽标，我正在按列表顺序显示该徽标。现在我正在做的是，我必须显示前 3 个徽标并等待几秒钟，然后隐藏这 3 个徽标并再次显示接下来的 3 个徽标等待几秒钟，然后显示接下来的 3 个徽标。我需要无限这个。

例如：

On the page load display first 3 logo

1 2 3

//wait for the second

1 2 3   // hide this
4 5 6   // display this
7 8 9   // hide this

//wait for second  
1 2 3   // hide this
4 5 6   // hide this
7 8 9   // display this

// wait for second
1 2 3   // display this
4 5 6   // hide this
7 8 9   // hide this

I need infinite.

我试过这段代码，但它不起作用。

ul {
  list-style: none;
  width: 100%;
  position: relative;
}

ul li {
  display: inline-block;
  width: 33%;
  animation-iteration-count: infinite;
  animation-timing-function: ease-in-out;
  opacity: 0;
  animation-name: fadeIn;
}

ul li img {
  width: 250px;
}


/*Animated Logos*/

@keyframes fadeIn {
  0% {
    opacity: 0;
  }
  6% {
    opacity: 1;
  }
  27% {
    opacity: 1;
  }
  33% {
    opacity: 0;
  }
}

.row--animated li:nth-of-type(-n+3) {
  animation-duration: 4s;
}

.row--animated li:nth-child(4),
.row--animated li:nth-child(5),
.row--animated li:nth-child(6) {
  animation-duration: 6s;
}

.row--animated li:nth-last-child(-n+3) {
  animation-duration: 8s;
  /*position: absolute;*/
}

<div class="row--animated">
  <ul>
    <li><img src="//placehold.it/450x280?text=Image 1" /></li>
    <li><img src="//placehold.it/450x280?text=Image 2" /></li>
    <li><img src="//placehold.it/450x280?text=Image 3" /></li>
    <li><img src="//placehold.it/450x280?text=Image 4" /></li>
    <li><img src="//placehold.it/450x280?text=Image 5" /></li>
    <li><img src="//placehold.it/450x280?text=Image 6" /></li>
    <li><img src="//placehold.it/450x280?text=Image 7" /></li>
    <li><img src="//placehold.it/450x280?text=Image 8" /></li>
    <li><img src="//placehold.it/450x280?text=Image 9" /></li>
  </ul>
</div>

你能帮我解决这个问题吗？

Update：这个片段就是我想你想要的，请注意我稍微更改了 HTML 以便我可以操纵元素的大小和显示，已实现只有 CSS3，深受此 codepen:

启发

.slider {
  width: 900px;
  margin: 0 auto;
}
.slide {
  position: absolute;
  display: grid;
  grid-template-columns: auto auto auto;
  grid-gap: 10px;
}

.slide img {
  width: 100;
  height: auto;
}

.slide1 {
  animation: fade 8s infinite;
  -webkit-animation: fade 8s infinite;
}
.slide2 {
  animation: fade2 8s infinite;
  -webkit-animation: fade2 8s infinite;
}
.slide3 {
  animation: fade3 8s infinite;
  -webkit-animation: fade3 8s infinite;
}
@keyframes fade {
  0% {
    opacity: 1;
  }
  33.333% {
    opacity: 0;
  }
  66.666% {
    opacity: 0;
  }
  100% {
    opacity: 1;
  }
}
@keyframes fade2 {
  0% {
    opacity: 0;
  }
  33.333% {
    opacity: 1;
  }
  66.666% {
    opacity: 0;
  }
  100% {
    opacity: 0;
  }
}
@keyframes fade3 {
  0% {
    opacity: 0;
  }
  33.333% {
    opacity: 0;
  }
  66.666% {
    opacity: 1;
  }
  100% {
    opacity: 0;
  }
}

您可以使用 display-grid 强制将元素排成一行。

并且您可以使用动画的属性来获得这种效果，但是所有元素的动画持续时间应该相同；从一个到另一个的变化是延迟，使然后处于动画的不同阶段：

ul {
  list-style: none;
  width: 100%;
  position: relative;
  display: grid;
}

ul li {
  display: inline-block;
  width: 30%;
  opacity: 0.2;
  animation: fadeInSlow ease-in-out 6s infinite;
  background-color: blue;
  height: 50px;
  grid-row: 1;
}

@keyframes fadeIn {
  0% {
    opacity: 0;
  }
  6% {
    opacity: 1;
  }
  27% {
    opacity: 1;
  }
  33% {
    opacity: 0;
  }
}

@keyframes fadeInSlow {
  0% {
    opacity: 0;
  }
  12% {
    opacity: 1;
  }
  21% {
    opacity: 1;
  }
  33%, 100% {
    opacity: 0;
  }
}

li:nth-child(4),
li:nth-child(5),
li:nth-child(6) {
  animation-delay: -4s;
}

li:nth-child(7),
li:nth-child(8),
li:nth-child(9) {
  animation-delay: -2s;
}

li:nth-child(3n+1) {
  grid-column: 1;
}

li:nth-child(3n+2) {
  grid-column: 2;
}

li:nth-child(3n+3) {
  grid-column: 3;
}

<div class="row--animated">
  <ul>
    <li>1</li>
    <li>2</li>
    <li>3</li>
    <li>4</li>
    <li>5</li>
    <li>6</li>
    <li>7</li>
    <li>8</li>
    <li>9</li>
  </ul>
</div>
