<!-- 一种让 slider 下标和对应档位对齐的奇技淫巧:
在其下方放置 flex 容器,其中放置 space-between 的若干 label。此时由于文字宽度的影响无法真正对齐产生偏移。
考虑将每个 label 实际大小设为 0这样 label 可以实际对齐;放置其 absolute 的子元素,其中放置实际要显示的文字,
该 span 通过指定 left 和 translate 可以实现文字中线和父元素对齐,从而实现文字和 slider 档位对齐,作为 slider 刻度。
此外,注意 x 轴 padding 应该设为 slider 上按钮半径大小,因为 slider 实际开始位置不是该元素最左端,而是滑块在最左端时的中心点。
