I build what's on the above screenshot using CSS grid, but failing to do this with flexbox.

.grid { display: grid; height: 100%; grid-template-columns: 2rem repeat(2, auto) 2rem; grid-template-rows: 4rem 4rem auto; background-color: #fff; } .layer1 { background-color: rgb(64, 213, 187); grid-column-start: 1; grid-column-end: span 3; grid-row-start: 1; grid-row-end: span 3; }

推荐答案

注意：问题询问有关沿 z轴堆叠柔性物品的问题。如果您是来这里沿着 y轴寻找将弹性项目彼此叠放的，请参阅此文章：防止从渲染一侧到另一侧的弹性项目。

NOTE: This question asks about stacking flex items along the z-axis. If you came here looking for "Stacking flex items on top of each other" along the y-axis, see this post instead: prevent flex items from rendering side to side.

Flexbox的设计使元素沿列或行对齐。它不是为堆栈而设计的。

Flexbox is designed to align elements along columns or rows. It is not designed for stacking.

CSS Grid非常适合这种事情。

CSS Grid, however, is perfect for this sort of thing.

Grid的CSS替代方法是绝对定位：

A CSS alternative to Grid would be absolute positioning:

（请注意，当弹性商品已完全定位，它不再接受大多数弹性属性。）

(Note that when a flex item is absolutely positioned, it no longer accepts most flex properties.)

article { display: flex; height: 100vh; position: relative; } section:nth-child(1) { flex: 1; background-color: turquoise; } section:nth-child(2) { position: absolute; top: 50px; left: 50px; right: 0; bottom: 0; background-color: salmon; } section:nth-child(3) { position: absolute; top: 100px; left: 250px; right: 0; bottom: 0; background-color: thistle; } body { margin: 0; }
