我使用嵌套计数器和范围来创建有序列表:
ol {
counter-reset: item;
padding-left: 10px;
}
li {
display: block
}
li:before {
content: counters(item, ".") " ";
counter-increment: item
}
<ol>
<li>one</li>
<li>two</li>
<ol>
<li>two.one</li>
<li>two.two</li>
<li>two.three</li>
</ol>
<li>three</li>
<ol>
<li>three.one</li>
<li>three.two</li>
<ol>
<li>three.two.one</li>
<li>three.two.two</li>
</ol>
</ol>
<li>four</li>
</ol>
我期待以下结果:
1. one
2. two
2.1. two.one
2.2. two.two
2.3. two.three
3. three
3.1 three.one
3.2 three.two
3.2.1 three.two.one
3.2.2 three.two.two
4. four
相反,这就是我看到的(编号错误):
1. one
2. two
2.1. two.one
2.2. two.two
2.3. two.three
2.4 three <!-- this is where it goes wrong, when going back to the parent -->
2.1 three.one
2.2 three.two
2.2.1 three.two.one
2.2.2 three.two.two
2.3 four
我不知道,有没有人知道哪里出错了?

使用此样式仅更改嵌套列表:
ol {
counter-reset: item;
}
ol > li {
counter-increment: item;
}
ol ol > li {
display: block;
}
ol ol > li:before {
content: counters(item, ".") ". ";
margin-left: -20px;
}

检查一下:
您的问题似乎已修复。
为我显示的内容(在Chrome和Mac OS X下)
1. one
2. two
2.1. two.one
2.2. two.two
2.3. two.three
3. three
3.1 three.one
3.2 three.two
3.2.1 three.two.one
3.2.2 three.two.two
4. four
代替:
<li>Item 1</li>
<li>Item 2</li>
<ol>
<li>Subitem 1</li>
<li>Subitem 2</li>
</ol>
执行:
<li>Item 1</li>
<li>Item 2
<ol>
<li>Subitem 1</li>
<li>Subitem 2</li>
</ol>
</li>
答案 3 :(得分:6)
这是一个很好的解决方案!使用一些额外的CSS规则,您可以将其格式化,就像MS Word大纲列表中有一个悬挂的第一行缩进:
OL {
counter-reset: item;
}
LI {
display: block;
}
LI:before {
content: counters(item, ".") ".";
counter-increment: item;
padding-right:10px;
margin-left:-20px;
}

我最近遇到过类似的问题。修复方法是将有序列表中li项的显示属性设置为list-item,而不是display block,并确保ol的display属性不是list-item。即
li { display: list-item;}
这样,html解析器将所有li视为列表项并为其分配适当的值,并根据您的设置将ol视为内联块或块元素,并且不会尝试分配任何li计算它的价值。

Moshe的解决方案很棒,但是如果您需要将列表放在div
中,问题可能仍然存在。 (阅读:CSS counter-reset on nested list)
此样式可以防止该问题:
ol > li {
counter-increment: item;
}
ol > li:first-child {
counter-reset: item;
}
ol ol > li {
display: block;
}
ol ol > li:before {
content: counters(item, ".") ". ";
margin-left: -20px;
}
<ol>
<li>list not nested in div</li>
</ol>
<hr>
<div>
<ol>
<li>nested in div</li>
<li>two
<ol>
<li>two.one</li>
<li>two.two</li>
<li>two.three</li>
</ol>
</li>
<li>three
<ol>
<li>three.one</li>
<li>three.two
<ol>
<li>three.two.one</li>
<li>three.two.two</li>
</ol>
</li>
</ol>
</li>
<li>four</li>
</ol>
</div>
您还可以在li:before
上设置计数器重置。

在完成其他答案之后,我想到了这一点,只需将类nested-counter-list
应用于根ol
标记:
密码:
ol.nested-counter-list {
counter-reset: item;
li {
display: block;
&::before {
content: counters(item, ".") ". ";
counter-increment: item;
font-weight: bold;
}
}
ol {
counter-reset: item;
& > li {
display: block;
&::before {
content: counters(item, ".") " ";
counter-increment: item;
font-weight: bold;
}
}
}
}
css代码:
ol.nested-counter-list {
counter-reset: item;
}
ol.nested-counter-list li {
display: block;
}
ol.nested-counter-list li::before {
content: counters(item, ".") ". ";
counter-increment: item;
font-weight: bold;
}
ol.nested-counter-list ol {
counter-reset: item;
}
ol.nested-counter-list ol > li {
display: block;
}
ol.nested-counter-list ol > li::before {
content: counters(item, ".") " ";
counter-increment: item;
font-weight: bold;
}
ol.nested-counter-list {
counter-reset: item;
}
ol.nested-counter-list li {
display: block;
}
ol.nested-counter-list li::before {
content: counters(item, ".") ". ";
counter-increment: item;
font-weight: bold;
}
ol.nested-counter-list ol {
counter-reset: item;
}
ol.nested-counter-list ol>li {
display: block;
}
ol.nested-counter-list ol>li::before {
content: counters(item, ".") " ";
counter-increment: item;
font-weight: bold;
}
<ol class="nested-counter-list">
<li>one</li>
<li>two
<ol>
<li>two.one</li>
<li>two.two</li>
<li>two.three</li>
</ol>
</li>
<li>three
<ol>
<li>three.one</li>
<li>three.two
<ol>
<li>three.two.one</li>
<li>three.two.two</li>
</ol>
</li>
</ol>
</li>
<li>four</li>
</ol>
如果您需要在嵌套列表的计数器末尾加上.
,请使用以下代码:
ol.nested-counter-list {
counter-reset: item;
}
ol.nested-counter-list li {
display: block;
}
ol.nested-counter-list li::before {
content: counters(item, ".") ". ";
counter-increment: item;
font-weight: bold;
}
ol.nested-counter-list ol {
counter-reset: item;
}
<ol class="nested-counter-list">
<li>one</li>
<li>two
<ol>
<li>two.one</li>
<li>two.two</li>
<li>two.three</li>
</ol>
</li>
<li>three
<ol>
<li>three.one</li>
<li>three.two
<ol>
<li>three.two.one</li>
<li>three.two.two</li>
</ol>
</li>
</ol>
</li>
<li>four</li>
</ol>
答案 7 :(得分:0)
一种简单和标准的解决方案,用于增加数字并在最后保留点。即使您正确使用了CSS,如果您的HTML不正确,它也将无法工作。见下文。
ol {
counter-reset: item;
}
ol li {
display: block;
}
ol li:before {
content: counters(item, ". ") ". ";
counter-increment: item;
}
ol {
counter-reset: item;
li {
display: block;
&:before {
content: counters(item, ". ") ". ";
counter-increment: item
}
}
}
如果添加子项,请确保其在父项li
下。
<!-- WRONG -->
<ol>
<li>Parent 1</li> <!-- Parent is Individual. Not hugging -->
<ol>
<li>Child</li>
</ol>
<li>Parent 2</li>
</ol>
<!-- RIGHT -->
<ol>
<li>Parent 1
<ol>
<li>Child</li>
</ol>
</li> <!-- Parent is Hugging the child -->
<li>Parent 2</li>
</ol>
