Où l’utiliser
Des chiffres qui flottent, c’est léger et un peu absurde, exactement l’ambiance qu’il faut quand quelqu’un vient de cliquer sur un lien mort. Le visiteur ne se sent pas fautif. Un studio produit, une application mobile ou une boutique en ligne à l’image décontractée peuvent adopter cette page 404 en apesanteur sans qu’elle détonne.
Elle est violette par défaut, mais reste lisible avec presque n’importe quelle couleur : reprenez celle de votre bouton principal. Si le mouvement détourne l’attention du texte, baissez un peu la vitesse. Ce qui compte vraiment ici, c’est le bouton de retour.
