CSS講解

示意圖

透過在box定義相對定位，並在content-box以及img-box設定絕對定位來讓它們重和

重要代碼塊

  1. 當hover到box時要讓content-box營造從左到右出現並在消失是從右邊收合

    .content-box {
      transition: transform 0.5s;
      /*將元素以開窗戶的方式顯現(如果沒有設定origin的話)*/
      transform: scaleX(0);
      /*消失是在右邊*/
      transform-origin: right; 
    }
    .box:hover .content-box {
      /*將元素以開窗戶的方式顯現(如果沒有設定origin的話)*/
      transform: scaleX(1); 
      /*消失是在左邊*/
      transform-origin: left;
    }

  2. 當hover到的時候再讓文字塊顯現(使用opacity)

    設置延遲時間，讓用戶產生打開才顯現的感覺.content-box .content {
      opacity: 0;
    }

    .box:hover .content-box .content{
      opacity: 1;
      /*設置延遲時間，讓用戶產生打開才顯現的感覺*/
      transition: all 0.5s 0.3s; 
    }
