上面的 .pt-page-ontop 样式用于某些页面过渡效果,即我们需要让一个页面留在另一个页面的顶部。下面是一个代码例子,展示了动画类和关键帧动画,在不同方向上缩放网页和以及淡入淡出效果:
CSS Code复制内容到剪贴板
/* scale and fade */
.pt-page-scaleDown {
animation: scaleDown .7s ease both;
}
.pt-page-scaleUp {
animation: scaleUp .7s ease both;
}
.pt-page-scaleUpDown {
animation: scaleUpDown .5s ease both;
}
.pt-page-scaleDownUp {
animation: scaleDownUp .5s ease both;
}
.pt-page-scaleDownCenter {
animation: scaleDownCenter .4s ease-in both;
}
.pt-page-scaleUpCenter {
animation: scaleUpCenter .4s ease-out both;
}
/************ keyframes ************/
/* scale and fade */
@keyframes scaleDown {
to { opacity: 0; transform: scale(.8); }
}
@keyframes scaleUp {
from { opacity: 0; transform: scale(.8); }
}
@keyframes scaleUpDown {
from { opacity: 0; transform: scale(1.2); }
}
@keyframes scaleDownUp {
to { opacity: 0; transform: scale(1.2); }
}
@keyframes scaleDownCenter {
to { opacity: 0; transform: scale(.7); }
}
@keyframes scaleUpCenter {
from { opacity: 0; transform: scale(.7); }
}
对于本演示的目的,我们采用了相应的动画类应用到当前页以及即将切换进来的页面,例如:
