本次项目中动画放大缩小代码小结

.fix .phone{ -moz-animation: myfirst 1s infinite; -webkit-animation: myfirst 1s infinite; -o-animation: myfirst 1s infinite; animation: myfirst 1s infinite;}
@keyframes myfirst{
0% { transform: scale(.8); }
50% { transform: scale(1); }
100% { transform: scale(.8); }
}
@-moz-keyframes myfirst{
0%	{-moz-transform: scale(.8);}
50%	{-moz-transform: scale(1);}
100%	{-moz-transform: scale(.8);}
}
@-webkit-keyframes myfirst{
0%	{-webkit-transform: scale(.8);}
50%	{-webkit-transform: scale(1);}
100%	{-webkit-transform: scale(.8);}
}

@-o-keyframes myfirst{
0%	{-o-transform: scale(.8);}
50%	{-o-transform: scale(1);}
100%	{-o-transform: scale(.8);}
}
