css文字从右向左滚动效果，具体代码如下
.u-notice-content {
line-height: 1;
white-space: nowrap;
font-size: 26rpx;
animation: u-loop-animation 10s linear infinite both;
text-align: right;
padding-left: 100%;
}
@keyframes u-loop-animation {
0% {
transform: translate3d(0, 0, 0);
}
100% {
transform: translate3d(-100%, 0, 0);
}
}
