Flexbox 重叠绝对定位子级

Question

我遇到了flexbox 带有绝对定位子级的容器的问题。

FIDDLE;如果窗口变小（宽度）标题变小，那是绝对正确的，问题出在与其他手表重叠的数字上。我对z-Index、background-color 进行了一些测试，但没有任何效果。

Answer 1

将overflow:hidden; 添加到.stopwatch__counter

.stopwatch__counter {
    background-color: #333333;
    padding: 15px;
    flex-grow: 1;
    text-align: center;
    color: #ffffff;
    display: flex;
    overflow:hidden;
    align-items: center;
    justify-content: center; }
