Question

我附上了我的HTML和CSS文件。

我需要的是什么：＆＃34; a。＆＃34;应该包含在（）中，如（a）和＆＃34; i＆＃34;在下一个级别为（i）和在＆＃34; i＆＃34;列表编号显示为＆＃34; 1＆＃34;应显示为（aa），然后显示为（ab），依此类推。

我希望对齐保持不变，只有样式才能与我的期望一致。怎么做？

注意：解决方案不应该导致对齐方式的变化而且不允许使用JavaScript

p.p1 {
  text-indent: 0cm;
  margin-left: 36;
  word-break: break-all;

li {
  list-style-position: inside;
  margin-top: 10pt;
  word-break: break-all;
}
li::before {

Answer 1

据我所知，目前无法使用大括号设置列表编号的样式。 There was a section in the CSS3 spec about custom defining counter styles and using it along with list-style-type但它似乎还没有完全实现（至少不是跨浏览器），因此最好的办法是使用计数器自定义样式列表编号，而不是使用默认的列表样式类型。

使用计数器时，我们只需为每个级别分配一个计数器，在相应的ol标记处重置/初始化计数器，每当遇到li时递增计数器的值并使用:before伪元素在文本之前显示计数器的值。使用伪元素的content属性显示计数器值，因此可以轻松添加大括号（就像执行字符串连接一样）。

对于（aa），（bb）样式，有定义的反式样式和类似varun aaruru在他的评论中提到过，没有预先定义的计数器/列表样式，这样的值只有在达到字母z之后。在默认的ol样式中，这可以通过给出起始值来完成，但它仍然不会产生括号，因此我们必须再次使用计数器。在计数器中，我们可以通过将计数器的初始值本身重置为26（z是第26个字母表）来实现此目的。

以下代码段会生成您要查找的输出。

  text-indent: 0cm;
  margin-left: 36;
  word-break: break-all;
}

  word-break: break-all;
}
li::before {
  content: "";
  width: 13pt;
  display: inline-block;
}
.ol1 {
  padding-left: 2pt;
}
.pNote {
  text-indent: 0cm;
  margin: 0cm 0cm 10pt;
}

/* initialize counters */

ol.a {
  counter-reset: list-item-level2;
}
ol.i {
  counter-reset: list-item-level3;
}
ol.aa {
  counter-reset: list-item-level4 26;
}

/* nullify default list styling */

ol.a li,
ol.i li,
ol.aa li {
  list-style-type: none;
}

/* reset the word break for pseudo elements */

ol.a li:before,

  word-break: normal;
}

/* increment the counters */

ol.a li {
  counter-increment: list-item-level2;
}
ol.i li {
  counter-increment: list-item-level3;
}
ol.aa li {
  counter-increment: list-item-level4;
}

/* display the counter values */

ol.a li:before {
  content: '('counter(list-item-level2, lower-latin)')';
  margin-right: 16px;
}
ol.i li:before {
  content: '('counter(list-item-level3, lower-roman)')';
  margin-right: 16px;
}
ol.aa li:before {
  content: '('counter(list-item-level4, lower-latin)')';
  margin-right: 28px;
}
