javascript - 删除 Ul 警报

Question

我在一行中有三个 ul。如果删除了另一个 ul li，我如何将 ul 滑动到左侧。这是它的外观示例。 (如果可能，纯 Javascript)。

.one {
  box-sizing: border-box;
  padding: 16px;
  width: 100%;
  background-color: red;
  color: #fff;
}
.two {
  box-sizing: border-box;
  padding: 16px;
  width: 100%;
  background-color: green;
  color: #fff;
}
.three {
  box-sizing: border-box;
  padding: 16px;
  width: 100%;
  background-color: blue;
  color: #fff;
}
.closebtn {
  float: right;
  font-size: 30px;
  font-weight: bold;
  cursor: pointer;
}
.closebtn:hover {
  color: #000;
}
ul {
  width: 25%;
  display: inline-block;
}

<ul>
<li class="one">
  <span onclick="this.parentElement.style.display = 'none';" class="closebtn">&times;</span>
  <p>To close this container, click on the X symbol to the right.</p>
</li>
<li class="two">
  <span onclick="this.parentElement.style.display = 'none';" class="closebtn">&times;</span>
  <p>To close this container, click on the X symbol to the right.</p>
</li>

  <p>To close this container, click on the X symbol to the right.</p>

您可以使用 max-width 而不是 ul 上的宽度。检查下面更新的代码段

.one {
  box-sizing: border-box;
  padding: 16px;
  width: 100%;
  background-color: red;
  color: #fff;
}
.two {
  box-sizing: border-box;
  padding: 16px;
  width: 100%;
  background-color: green;
  color: #fff;
}
.three {
  box-sizing: border-box;
  padding: 16px;
  width: 100%;
  background-color: blue;
  color: #fff;
}
.closebtn {
  float: right;
  font-size: 30px;
  font-weight: bold;
  cursor: pointer;
}
.closebtn:hover {
  color: #000;
}
ul {
  max-width: 25%;
  display: inline-block;
}

<ul>
<li class="one">
  <span onclick="this.parentElement.style.display = 'none';" class="closebtn">&times;</span>
  <p>To close this container, click on the X symbol to the right.</p>
</li>
<li class="two">
  <span onclick="this.parentElement.style.display = 'none';" class="closebtn">&times;</span>
  <p>To close this container, click on the X symbol to the right.</p>
</li>
<li class="three">
  <span onclick="this.parentElement.style.display = 'none';" class="closebtn">&times;</span>
  <p>To close this container, click on the X symbol to the right.</p>
