Introduction détaillée aux détails de l'exemple de code de l'animation d'engrenage simulé HTML5

Il s'agit d'un effet spécial d'animation d'engrenage basé sur HTML5. Nous convertissons les principes physiques de la rotation des engrenages en code HTML5 et implémentons l'effet d'animation de la rotation des engrenages simulée sur la page Web. La plus grande caractéristique de cette animation d'engrenage est qu'elle est composée de plusieurs engrenages, ce qui augmente considérablement les exigences de l'algorithme pour la transmission des engrenages. De plus, nous n'avons pas utilisé JavaScript, mais du CSS3 pur pour l'implémenter.
