How to add section numbers (1.2, 3.4.1) automatically using CSS?

I currently have

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;}

How to modify them so section numbers such as 1.3, 2.4.5 are automatically constructed depending on the nesting level and order of appearance of the section headers?





should show

  1. heading21

    1.1 heading31

  2. heading22

or something along those lines.

Solution :

Hey now you can used CSS counter-increment Property

As like this Css

   body {counter-reset:section;}
    h1 {counter-reset:subsection;}
    content:"Section " counter(section) ". ";
    content:counter(section) "." counter(subsection) " ";


<p><b>Note:</b> IE8 supports these properties only if a !DOCTYPE is specified.</p>
