HTML Style alignSelf用法及代碼示例


DOM樣式alignSelf屬性用於設置或返回柔性容器內選定項目的對齊方式。

用法:

  • 獲取alignSelf屬性
    object.style.alignSelf
  • 設置alignSelf屬性
    object.style.alignSelf = "auto | stretch | center | flex-start |
flex-end | baseline | initial | inherit"

屬性值：


  • auto:元素繼承父容器的“ align-items”屬性，如果沒有父容器，則將其設置為“拉伸”。這是默認樣式。
  • stretch:這用於拉伸物品以適合容器。
  • center:這用於使項目在容器中居中。
  • flex-start：這用於將項目定位在容器的開頭
  • flex-end：這用於將商品放置在容器的末端。
  • baseline:這用於將項目定位在容器的基線。
  • initial:這用於將此屬性設置為其默認值。
  • inherit:這將從其父項繼承該屬性。

示例1：使用自動值。
