Google ドキュメントの文書に章節番号を自動的につける

ラベル参照などはできないけれど、番号をつけるだけなら CSS でできる。

 body {
  counter-reset: chapter section subsection;
 }

 H2:before {
   counter-increment: chapter;
   content: "第" counter(chapter) "章 ";
 }

 h2 {
   counter-reset: section subsection;
 }

 H3:before {
   counter-increment: section;
   content: counter(chapter) "." counter(section) " ";
 }

 h3 {
   counter-reset: subsection;
 }

 H4:before {
   counter-increment: subsection;
   content: counter(chapter) "." counter(section) "." counter(subsection) " ";
 }

H1 はタイトル用。
