如何使用CSS自动添加节号(1.2,3.4.1)?
我目前有
h1, h2, h3, h4 {
font-weight: normal;
}
h1 { font-size: 140%; }
h2 { font-size: 120%; color:#049;}
h3 { font-size: 110%; color:#06C;}
h4 { font-size: 105%; color:#09C;}
如何修改它们以便根据嵌套级别和节标题的出现顺序自动构建1.3,2.4.5等节编号?
...
<h2>heading21</h2>
...
<h3>heading31</h3>
...
<h2>heading22</h2>
应该显示
heading21
1.1 heading31
heading22
或类似的东西。

嘿,现在你可以使用 CSS反增量属性
就像这样 的的CSS 强>
body {counter-reset:section;}
h1 {counter-reset:subsection;}
h1:before
{
counter-increment:section;
content:"Section " counter(section) ". ";
font-weight:bold;
}
h2:before
{
counter-increment:subsection;
content:counter(section) "." counter(subsection) " ";
}
<强> HTML 强> **
<p><b>Note:</b> IE8 supports these properties only if a !DOCTYPE is specified.</p>

要回答以下问题:“我只有一个h2,如何抑制前导1.,请在样式选择器之前更改h2:before,以便h2必须遵循h1:
h1:before > h2:before {
// your h2 attributes go here
}
