html - 需要帮助获得部分和子部分的正确缩进

Question

为了快速了解我遇到的问题，首先快速查看下面的比较图片，它显示了我想要实现的压痕效果与我实际得到的效果。

我试图让每个子部分中的所有行在文本内容的第一个字符上排列，缩进超过部分符号占用的空间。

我相信这类似于悬挂缩进，除了它更聪明，因为它知道每个部分符号的字符串长度并相应地进行调整。我不确定这种效果的正确名称是什么（如果有的话）。

我已经尝试过使用text-indent和其他属性，但没有成功。文本是带有子项的有序列表。当枚举为1.1.2或1.1文本缩进/对齐未实现如上所述。

ol {
  counter-reset: item;
}

li {
    display: block;
}

li:before {
  content: counters(item, ".") " ";
  counter-increment: item;
}

<div class ="all-text">
  <div align="center" ><b>TITLE</b></div>
  <br><br>
  <div class ="lista-principal">  <!-- div da lista ordenada principal -->
  <ol> <!-- Lista ordenada principal -->
  <!-- Inicio do ITEM 1 da lista principal P1 -->
    <li> <span>TITULO</span> 
        <ol> 
           <li>
            But I must explain to you how all this mistaken idea of denouncing pleasure and praising pain was born and I will give you a complete account of the system, and expound the actual teachings of the great explorer of the truth, the master-builder of human happiness. No one rejects, dislikes, or avoids pleasure itself, because it is pleasure, but because those who do not know how to pursue pleasure rationally encounter consequences that are extremely painful. Nor again is there anyone who loves or pursues or desires to obtain pain of itself, because it is pain, but because occasionally circumstances occur in which toil and pain can procure him some great pleasure. To take a trivial example, which of us ever undertakes laborious physical exercise, except to obtain some advantage from it? But who has any right to find fault with a man who chooses to enjoy a pleasure that has no annoying consequences, or one who avoids a pain that produces no resultant pleasure?"

这段代码对我有用：

css

ol {
  counter-reset: item;
}

li {
    display: block;
    position: relative;
    padding-left: 15px;
}

ol ol li{
    padding-left: 30px;
}
li:before {
  content: counters(item, ".") " ";
  counter-increment: item;
  position: absolute;
  left: 0;
  top: 0;
}

html:

<div class ="all-text">
  <div align="center" ><b>TITLE</b></div>
  <br><br>
  <div class ="lista-principal">  <!-- div da lista ordenada principal -->
  <ol> <!-- Lista ordenada principal -->
  <!-- Inicio do ITEM 1 da lista principal P1 -->
    <li> <span>TITULO</span> 
        <ol> 
           <li>
