fluentTextareaFocusUnderlineExit top-level constant
FluentMotionSpec
const fluentTextareaFocusUnderlineExit
The focus underline leaving. Upstream's resting ::after rule transitions
transform over durationUltraFast on curveAccelerateMid — four times
faster than fluentTextareaFocusUnderlineEnter, and accelerating rather
than decelerating. The asymmetry is upstream's; do not "tidy" it.
An alias of fluentInputFocusUnderlineExit, for the reason given on fluentTextareaFocusUnderlineEnter.
Implementation
const FluentMotionSpec fluentTextareaFocusUnderlineExit =
fluentInputFocusUnderlineExit;
