定義

justify-content會沿著main-axis對齊

快速複習

  • 【預設】flex-direction: row,main-axis為由左至右→→→
  • flex-direction: column,main-axis為由上至下↓↓↓

main-axis為由左至右的情況下(Default)

justify-content: space-around

手法近似於每個item得到一樣的margin-left跟margin-right。
由於第2-9個item的兩邊會重疊鄰居的margin,所以空隙為2倍。
第1個與第10個item的margin沒有鄰居加持,所以與邊界的空隙只有1倍。

2個注意事項

  • 需要指定min-height
  • 每個item不能給太高(加總高須低於min-height)
