Menú radial animado.

Un menú radial puro basado en HTML / CSS que expande / contrae elementos de menú secuencialmente con animaciones suaves de CSS3.

Incluye el Font Awesome 4 opcional para los íconos del menú.

Utiliza la casilla de verificación y el truco de la etiqueta para crear un botón de alternar que le permite abrir / cerrar el menú radial.

Crea elementos de menú que se muestran alrededor del botón de alternar.

Habilite el menú radial con magia CSS / CSS3.
