數位相簿很上手

一、水平對齊: Bootstrap 4 一樣利用了 Flexbox 的特性實現水平對齊。

使用 flexbox 容器上的 justify-content 通用類別改變 flex 物件在主軸上的對齊(x軸開始,如果 flex-direction: column,則為 y 軸)。從 start(瀏覽器預設)、 end、center、between、或 around 中選擇。

  1. justify-content-start:靠左對齊(預設)
  2. justify-content-center:置中對齊
  3. justify-content-end:靠右對齊
  4. justify-content-around:分散對齊(含左右)
  5. justify-content-between:分散對齊(不含左右)
二、程式碼
