我预计圆圈是1,2,3和4,但输出是4,1,2和3。我不知道是否是position:absolute;导致它发生。欢迎收到任何反馈。

.circle:nth-child(n)选择满足以下条件的元素:circle你的 DOM 看起来像这样:
.q-card__section// :nth-child(1).circle:内容 1 // :nth-child(2).circle:内容 2 // :nth-child(3).circle:内容 3 // :nth-child(4).circle:内容 4 // :nth-child(5)您可能会得到预期结果 通过将
.circle包装在单独的容器中:.q-card__section// :nth-child(1)div// :nth-child(2).circle:内容 1 // :nth-child(1).circle:内容 2 // :nth-child(2).circle:内容 3 // :nth-child(3).circle:内容 4 // :nth-child(4)
