html滚动效果代码}
.risk-active-line-f {
left: 166px;
}
.risk-active-line-r {
left: 288px;
}
}
.risk-cont {
color: #fff;
}
</style>
需要注意的是
transition: all 0.3s ease;
}
.risk-active-line-f {
left: 166px;
}
.risk-active-line-r {
left: 288px;
}
优化后
.risk-active-line-f {
transform: translate3d(0, 0, 0);
}
.risk-active-line-r {
transform: translate3d(120px, 0, 0);  }
这种写法⽐上⾯相对好操作
