Looking for ways to auto-number sections.

I'm looking for a way to number section headings automatically, so

# Chapter A

## Section B

## Section C

looks like
1. Chapter A
1.1 Section B
1.2 Section C

I found this on StackOverflow. Adding the following to css works in preview but in the generated PDF all counters are 0 or 1. Suggestions?
(After posting this I saw a tip which is similar to the css below. That tip shows the same behaviour for me: all counters are 0 or 1 only)

body {
    counter-reset: h1

h1 {
    counter-reset: h2

h2 {
    counter-reset: h3

h3 {
    counter-reset: h4

h1:before {
    counter-increment: h1;
    content: counter(h1) ". "

h2:before {
    counter-increment: h2;
    content: counter(h1) "." counter(h2) ". "

h3:before {
    counter-increment: h3;
    content: counter(h1) "." counter(h2) "." counter(h3) ". "

h4:before {
    counter-increment: h4;
    content: counter(h1) "." counter(h2) "." counter(h3) "." counter(h4) ". "

    What you have should work. If you could show me a sample document and
    the resulting PDF output, I'd be happy to test it out.

    I've tried a few different settings and my PDF always comes out like the
    attached (with 1.2 properly numbered). If you want to test further, I'd
    need the output of Help->Report an Issue so I can see if there's a
    particular setting that might be throwing it off for you.

    Are you loading the CSS file in your archive as a custom style, or
    adding it to Additional CSS in Style preferences?

    Forget that question, it works for me either way. I'm really uncertain why you're running into this. One thing I'd have you try is going to the gear menu and turning outline mode on to Decimal format. Then use a default style and try exporting and see if counters work at that point.

    Also, if you export HTML (and be sure to check the box to include the stylesheet in the save panel), then open in a browser and print to PDF, does the resulting PDF maintain the count properly?

    Hi Brett,

    I will look into this as soon as I have some time, and I will let you know if I find anything.

    Thanks so far,
