继续自动排序列表编号

Question

我想知道如何在html中提供以下有序列表

1 Item 1
1A Item 2
1B Item 3
2 Item 4
2A Item 5
2B Item 6
2C Item 7
3 Item 8

Answer 1

像这样：

＆＃13;

＆＃13;

ol.number, ol.letter {
  list-style-type: none;
}  

ol.number {
  counter-reset: number;
}

ol.letter {
  counter-reset: letter;
}

ol.number > li:before {
  content: counter(number, decimal) " ";
  counter-increment: number;
}

ol.letter > li:before {
  content: counter(number, decimal) counter(letter, upper-alpha) " ";
  counter-increment: letter;
}

＆＃13;

<ol class="number">
  <li>Item 1</li>
  <ol class="letter">
    <li>Item 2</li>
    <li>Item 3</li>
  </ol>
  <li>Item 4</li>
  <ol class="letter">
    <li>Item 5</li>
    <li>Item 6</li>
    <li>Item 7</li>
  </ol>
  <li>Item 8</li>
</ol>

＆＃13;

＆＃13;

＆＃13;

或者，如果您更喜欢自动计算索引：

＆＃13;

＆＃13;

ol.number, ol.letter {
  list-style-type: none;
}  

ol.number {
  counter-reset: number index;
}

ol.letter {
  counter-reset: letter;
}

ol.number > li:before {
  content: counter(number, decimal) " ";
  counter-increment: number;
}

ol.letter > li:before {
  content: counter(number, decimal) counter(letter, upper-alpha) " ";
  counter-increment: letter;
}

ol.number li:after {
  content: " " counter(index, decimal);
  counter-increment: index;
}

＆＃13;

<ol class="number">
  <li>Item</li>
  <ol class="letter">
    <li>Item</li>
    <li>Item</li>
  </ol>
  <li>Item</li>
  <ol class="letter">
    <li>Item</li>
    <li>Item</li>
    <li>Item</li>
  </ol>
  <li>Item</li>
</ol>
