# Field validation (field-validation.js, VALIDATION_UX_PLAN.md)

# An invalid field gets a red border (and a ! for text fields); its message shows in one floating bubble for the
# focused or hovered field, so an error never pushes the form's rows apart. The script sets html.fv-ready; until
# then (or if it fails) the old inline messages show as before.
