1. **行內級元素**: 設置父元素的text-align: center
2. **塊級元素**:設置當前塊級元素(寬度) margin: 0 auto;
3. **絕對定位**元素**有寬度**情況下, **left0/right0/margin: 0 auto;**
4. **flex** justify-content: center
5.**translate**
>[success] # css -- 垂直居中
1. **絕對定位**，元素有**高度**情況下, top0/bottom0/margin: auto 0，缺點脫離標準流，必須給元素設置高度
2. **flex布局**
3. **translate**
