Question

我有一个有序列表，我想跳过特定项目的数字输出。

传统输出：

1. List item
2. List item
3. List item
4. List item
5. List item

期望的输出：

1. List item
2. List item
   Skipped list item
3. List item
4. List item
5. List item

这可以在CSS中实现吗？我之前发现了一个我不知道的<ol> "start" attribute，但似乎没有帮助我。

Answer 1

最简单的方法是从要跳过的项目中删除列表标记，并使用the value attribute设置下一个项目的编号（在HTML5中不会弃用/废弃）。例如：

<ol>
<li>List item
<li>List item
<li style="list-style-type: none">List item
<li value=3>List item
<li>List item
</ol>

Answer 2

另一种选择是使用CSS3计数器： demo

HTML

<ul>
<li>One</li>
<li>Two</li>
<li class="skip">Skip</li>
<li>Three</li>
<li>Four</li>
</ul>

CSS

ul {
    counter-reset:yourCounter;
}
ul li:not(.skip) {
    counter-increment:yourCounter;
    list-style:none;
}
ul li:not(.skip):before {
    content:counter(yourCounter) ".";
}
ul li.skip:before {
    content:"\a0\a0\a0"; /* some white-space... optional */
}

Answer 3

现在很简单。

只需将以下内容添加到.skip类中，并将.skip用于跳过的列表项：

ol li.skip {
    list-style-type:none;
    counter-increment:none;
}

HTML中的

将是：

<ol>
  <li>first list item</li>
  <li class="skip">2nd list item</li>
  <li>third list item</li>
</ol>

导致：

第一个清单项目第二个清单项目
第三个列表项

Answer 4

这是我的解决方案（仅限CSS），允许您从ol（有序列表）保持li（列表项）的正常使用。这意味着所有li项都是有意义的，并且没有任何项目与其邻居不相同。

下面的代码：

 .term-and-condition li {
    position: relative;
  }
  .term-and-condition ol ol {
    list-style-type: lower-latin;
  }
  .term-and-condition h2 {
    position: absolute;
    top: -2.4em;
    left: -1.5em;
  }
  .term-and-condition h3 {
    position: absolute;
    top: -2.4em;
    left: -1.5em;
  }
  .term-and-condition h2 + *,
  .term-and-condition h3 + * {
    margin-top: 4em;
  }

    <meta charset="UTF-8">

Answer 5

我尝试似乎起作用的一件事是添加了font-size：0。这可以应用于上述“ skip”类。

诚然，此解决方案虽然缺乏HTML的纯净性，但非常简单。
