我想从我的问题中添加一个字母到我的 -<li>元素中：<ol>

body { counter-reset: item; }

ol.numbered_style li:before
{
    counter-increment:item;
    margin-bottom:5px;
    margin-right:10px;
    content:counter(item);
    background:blue;
    border-radius:100%;
    color:white;
    width:1.2em;
    text-align:center;
    display:inline-block;
}
ol.numbered_style.start_3{
  counter-reset: item 2; 
}

ol.none, ul.none,ol.numbered_style { list-style: none; }
<ol class="numbered_style">
	<li>first</li>
	<li>second</li>
	<li>third  Lorem Ipsum
		<ol class="numbered_style start_3">
			<li>missing an a after the number</li>
			<li>missing a b after the number</li>
			<li>missing a c after the number</li>
		</ol>
	</li>
</ol>
我试过li::before { content: " a ";}了，但这没有用。我还想要一个解决方案，其中添加第二个计数器可以生成具有以下字母数字模式的下一个元素，例如list-style-type: lower-alpha;

当然，你可以做任何可以做的<ol>事情。

ol.numbered_style.start_3{
  counter-reset: item2; 
}

ol.numbered_style.start_3 li:before {
    counter-increment:item2;
    content:counter(item2, upper-latin);
}/* List Style Type========^----------^*/

计数器列表样式类型

  • 十进制 ------------------- 1, 2, 3, ...

  • 十进制前导零 -------------- 01, 02, 03, ... 09, 10, 11, ...

  • lower-alpha, lower-latin ----------- a, b, c, ... z, aa, ab, ...

  • 大写字母，大写拉丁字母 ---------- A, B, C, ... Z, AA, AB, ...

  • 小罗马 ------------------------ i, ii, iii, iv, v, vi, ...

  • upper-roman ------------------------ I, II, III, IV, V, VI, ...

  • 星号 ----------------------------- *, **, ***,...

试试这个：

ol.main {
  counter-reset: item;
}
ol.main li {
  counter-increment: item;
}
ol.numbered_style li:before {
  margin-bottom: 5px;
  margin-right: 10px;
  content: counter(item);
  background: blue;
  border-radius: 100%;
  color: white;
  width: 1.2em;
  text-align: center;
  display: inline-block;
}
ol.numbered_style ol.numbered_style li {
  counter-increment: subitem;
}
ol.numbered_style ol.numbered_style li:before {
  content: counter(item) counter(subitem, lower-alpha);
}
ol.none,
ul.none,
ol.numbered_style {
  list-style: none;
}
<ol class="main numbered_style">
  <li>first</li>
  <li>second</li>
  <li>third Lorem Ipsum
    <ol class="numbered_style">
      <li>missing an a after the number</li>
      <li>missing a b after the number</li>
      <li>missing a c after the number</li>
    </ol>
  </li>
</ol>

<hr>

<ol class="main numbered_style">
  <li>first</li>
  <li>second</li>
  <li>third Lorem Ipsum
    <ol class="numbered_style">
      <li>missing an a after the number</li>
      <li>missing a b after the number</li>
      <li>missing a c after the number</li>
    </ol>
  </li>
</ol>
