重新的标题：placing a div above another div through positioning

Question

将共享 div 定位为如上图所示对我来说是一个挑战。好吧，我尝试了 positionabsolute 与 bottom 和 left 调整 px 非常令人沮丧，但输出总是堆叠在顶部或底部。我怎样才能实现图片中类似的输出？

:root {
  --VeryDarkGrayishBlue: hsl(217, 19%, 35%);
  --DesaturatedDarkBlue: hsl(214, 17%, 51%);
  --GrayishBlue: hsl(212, 23%, 69%);
  --LightGrayishBlue: hsl(210, 46%, 95%);
}

Answer 1

我对代码进行了一些更改，并使用 absolute 使弹出窗口可见。

:root {
  --VeryDarkGrayishBlue: hsl(217, 19%, 35%);
  --DesaturatedDarkBlue: hsl(214, 17%, 51%);
  --GrayishBlue: hsl(212, 23%, 69%);
  --LightGrayishBlue: hsl(210, 46%, 95%);
}
