Dónde usarlo
Unos números flotando se sienten ligeros y un poco tontorrones, justo el ambiente que quieres cuando alguien acaba de pinchar un enlace roto. Le quita la culpa a quien visita. Un estudio de producto, una app móvil o una tienda online con una marca desenfadada pueden usar esta página 404 en gravedad cero sin que desentone.
Viene en violeta, pero se lee bien con casi cualquier color, así que ponle el de tu botón principal. Si el movimiento distrae del texto, baja un poco la velocidad: aquí lo que importa de verdad es el botón de vuelta.
