_sub-title(1)

_Like this, you put a space line under the sub-title and make a section to begin with space. This makes two sections. The first section has only the sub-title. The second section has only the paragraph.

_If you insert a space line to every paragraph, every paragraph has an anchor.

_sub-title(2)

_Please be careful that a line which doesn't begin with space becomes a sub-title.
