我附上了我的 HTML 和 CSS 文件。

我需要的是：“a”。应该像 (a) 一样包含在 () 中，并且下一级中的“i”作为 (i)，在“i”下，显示为“1”的列表编号应显示为 (aa)，然后显示为 (ab)，并且很快。

我希望对齐保持原样，并且只有样式可以根据我的期望进行更改。这个怎么做？

注意：该解决方案不应导致对齐方式发生变化，并且不允许使用 JavaScript

据我所知，目前无法使用大括号对列表编号进行样式设置。CSS3 规范中有一节关于自定义定义计数器样式并使用它，list-style-type但它似乎还没有完全实现（至少不是跨浏览器），所以你最好的选择是使用计数器来自定义样式列出数字而不是使用默认的列表样式类型。

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

对于 (aa), (bb) 样式，定义了 counter-style-type ，就像 varun aaruru 在他的评论中提到的那样，没有预定义的 counter/list 样式，只有在字母表之后才会出现这样的z值到达。在默认ol样式中，这可以通过给出一个起始值来完成，但它仍然不会产生括号，所以我们再次必须使用计数器。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）来实现这一点。

下面的代码片段产生您正在寻找的输出。

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 {
  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,
ol.i li:before,
ol.aa 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 {
