Question

我正在构建一个类似netflix的滑块，其中悬停的滑块项目会将其他滑块项目推到一边（取决于它们的位置）。（参见示例代码）

我无法找到以下情况的解决方案：

当我将第3项悬停时，所有其他项目都会按照我的要求被左侧和右侧推到一边。

当第2项悬停时，我希望第1项（或.item-left左边的任何项目）不移动（保持原位）。所有其他人都按计划行事。

当第4项悬停时，我希望第3/2/1项与未悬停时保持4相同的距离。第5项表现正确。

悬停物品需要留在浅蓝色区域（显示）。

我该怎么做才能做到这一点？欢迎任何帮助。

谢谢！

var slider = document.getElementById('sli');
var prev = document.getElementById('prev');
prev.addEventListener('click', prevC, false);
var next = document.getElementById('next');
next.addEventListener('click', nextC, false);

function prevC() {
  alert('-1')
}

function nextC() {
  alert('+1');
}

我确实说过，实际上并没有CSS唯一的解决方案，但似乎您可能会有点创意......

您可以利用-webkit-transform: scale CSS属性。

将您的ul和li视为：

<ul class="slider-content">
  <li id="1" class="slider-item">1</li>
  <li id="2" class="slider-item">2</li>
  <li id="3" class="slider-item">3</li>
  <li id="4" class="slider-item">4</li>
</ul>

我们可以添加一些CSS来修改他们的订单并修改他们的悬停

ul{
  list-style:none;
}

ul:hover li {
  -webkit-transform: translateX(-25%);
          transform: translateX(-25%);
}
ul:hover li:hover {
  -webkit-transform: scale(1.5);
          transform: scale(1.5);
  transition-duration: 0.1818181818s;
}
ul:hover li:hover ~ li {
  -webkit-transform: translateX(25%);
          transform: translateX(25%);
}

.slider-item {
  position: relative;
  vertical-align: middle;
  display: inline-block;
  list-style: none;
  width: 100px;
  height: 69px;
  /* background-color: black; */
  transition-duration: .3s;
  overflow: hidden;
  cursor: pointer;
  border: 1px solid rgba(205, 20, 20, .3);
}

.slider-content {
  display: block;
  margin-top: 34px;
  list-style: none;
  white-space: nowrap;
  transform: translateY(-50%) translateX(-100px);
  text-align: center;
}

<ul class="slider-content">
  <li id="1" class="slider-item">1</li>
  <li id="2" class="slider-item">2</li>
  <li id="3" class="slider-item">3</li>
  <li id="4" class="slider-item">4</li>
</ul>

这可以通过使用CSS中的animations和translate css的一些巧妙使用来实现。
