<baseline-position>
The <baseline-position> enumerated value type represents the baseline keyword values and first and last modifiers, used for the align-content, align-items, align-self, justify-items and justify-self properties as well as the place-content, place-items, and place-self shorthand properties.
The first and last values give a box a baseline alignment preference, defaulting to first if the modifier is omitted.
Syntax
<baseline-position> = [ first | last ]? && baseline
