Tarjeta de Navidad en CSS

Esta entrada en realidad tiene dos motivos, la primera es para desearles a todos y cada uno de los lectores de este blog, una feliz Navidad, pero m?s aun, que estas fechas sean un pretexto para reconciliarnos con quienes hemos discutido, disfrutar a nuestros seres queridos, y valorar todo aquello que tenemos para as? compartir con los dem?s un poco de lo mucho que la vida nos da.

?Feliz Navidad!

les desea Ciudad Blogger

El otro motivo es para compartirles esta tarjeta de navidad hecha s?lo con CSS, las ?nicas im?genes que hay en ella son la de los copos de nieve.
Es un peque?o experimento que hice basado con la nieve de Joshua Johnson y las esferas de Catalin Rosu, yo pr?cticamente s?lo le he a?adido algunos efectos de hover y los bordes.

Como est? hecho con CSS s?lo se ver? bien en navegadores modernos, as? que si lo ves medio abstracto ya sabes porqu� raz?n se ve as?.
El c?digo para copiar y pegar en una entrada es este:
