Markdown and slide syntax

Fit a large heading to the available width

Understand  and what to do when a heading becomes larger than expected.

Use `<!-- fit -->` to enlarge a short heading. — Emphasize short headings with fit, and split slides when content grows.

Use fit for short statements

Write #  Build less. to scale the heading to the available width. Fit does not represent a fixed font size.

Keep normal headings predictable

Do not use fit for long sentences or regular page headings. If it becomes unexpectedly large, remove fit, shorten the statement, or use a normal H1 or H2.
