重新的標題：placing a div above another div through positioning

Question

將共享div定位為如上圖所示對我來說是一個挑戰。好吧，我嘗試了positionabsolute與bottom和left調整px非常令人沮喪，但輸出總是堆疊在頂部或底部。我怎樣才能實現圖片中類似的輸出？ :root{--VeryDarkGrayishBlue:hsl(217,19%,35%);--DesaturatedDarkBlue:hsl(214,17%,51%);--GrayishBlue:hs

我對程式碼進行了一些更改，並使用 absolute 來讓彈出視窗可見。

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