覆盖（优化效果）el-dialog 的显示隐藏动画

element-ui dialog本身的动画效果基本就是没动画效果（摊手）

• 原来的弹窗动画

  

   

• 优化后的动画

 

 

 

• 只需加入以下这段css代码，非常简单

.el-dialog__wrapper {
	transition-duration: 0.3s;
}
.dialog-fade-enter-active{
	animation: none !important;
}
.dialog-fade-leave-active {
	transition-duration: 0.15s !important;
	animation: none !important;
  }

.dialog-fade-enter-active .el-dialog,
.dialog-fade-leave-active .el-dialog{
	animation-fill-mode: forwards;
}

.dialog-fade-enter-active .el-dialog{
	animation-duration: 0.3s;
	animation-name: anim-open;
	animation-timing-function: cubic-bezier(0.6,0,0.4,1);
}

.dialog-fade-leave-active .el-dialog{
	animation-duration: 0.3s;
	animation-name: anim-close;
}


@keyframes anim-open {
	0% { opacity: 0;  transform: scale3d(0, 0, 1); }
	100% { opacity: 1; transform: scale3d(1, 1, 1); }
}


@keyframes anim-close {
	0% { opacity: 1; }
	100% { opacity: 0; transform: scale3d(0.5, 0.5, 1); }
}
