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.
This is the Density::Pointer floor. A finger’s floor is
Density::target_least_px, which the emitted CSS carries as
TARGET_TOKEN. 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.
