Syntax

The keyword value normal, or a <number> optionally followed by an <integer>.

Values

<number>: Defines the size of the initial letter, in terms of how many lines it occupies. Negative values are not allowed.
<integer>: Defines the number of lines the initial letter should sink when the size of it is given. Values must be greater than zero. If omitted, it duplicates the size value, floored to the nearest positive whole number.

Formal definition
