pub const TARGET_LEAST: Step;Expand description
The least a pointer target may measure on a side.
WCAG 2.5.8 and the Macintosh HIG both put the floor at 24 CSS pixels, which
is Step::Broad at the default base. Named rather than written as a
number so a renderer spends the scale it already has: a second 24 in the
system is a second thing to keep in step with the first.
This is a floor on the contact patch, not on the type. Growing the text to
reach it is the wrong fix and belongs to nobody: see wiki
typography-standard, which owns the sizes.
Two things it deliberately does not say. It is not density-aware: a finger
wants nearer 44, and expressing that needs Density threaded through the
emitters, which they do not take today. And it does not reach a link inside
running prose, which must not grow, because a floor applied to every inline
anchor would set the leading of any paragraph carrying one.
