cartas-css

La flexibilidad de CSS es impresionante, hasta podemos crear un juego de cartas solamente con CSS y unas imágenes. Si deseamos crearlo, allá van los pasos:

Descarga estas imágenes y súbelas a tu servidor:

King.gif

Queen.gif

Jack.gif

cardback.gif

Ahora inserta este código CSS y Javascript en tu documento (El código Javascript es para hacer las cartas más grandes o pequeñas, el código CSS debe llevar por id “cardStyles”):

Select Code
<style id="cardStyles" type="text/css">
