animation css fonctionne pas

**ickyknox** · 21/04/2013, 16h38

bonjour à tous

sur cette page : http://codepen.io/anon/pen/edDng
le code proposé permet d'animer le menu comme un effet de pancarte qui se balance.

je suppose que cette animation est créé grace au code :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

	@keyframes swingdown {
		0% {
			opacity: .05;
			transform: rotateX(90deg);
		}
 
		30% {			
      opacity: 0.9999;
			transform: rotateX(-20deg);
			animation-timing-function: ease-in-out;
		}
 
		65% {
			transform: rotateX(20deg);
			animation-timing-function: ease-in-out;
		}
 
		100% {
			transform: rotateX(0);
			animation-timing-function: ease-in-out;
		}
	}

or quand je copie-colle le code sur un site vierge, ca ne fonctionne pas,
peut etre car le code n'est pas pris en compte.

Je voulais savoir si vous aviez une solution pourcorriger ce problème ?

je vous remercie
