# 🏅 Day 15 - 垂直水平置中

切版過程中，有時會碰到需要將內容垂直水平置中的狀況，以往實現起來會相對麻煩，如今我們可以利用 flex 技巧來快速達成。
### Flex 基本介紹
又稱 Flexbox（彈性盒子），是一種方便好用的排版語法，只需設定 `display: flex` 將區塊轉為 flex 元素，即可使用相關 flex 語法來排版，以下介紹主要對齊屬性
### justify-content
用於對齊區塊 X 軸，常用屬性值：
- center：水平置中
- space-between：貼齊父層兩側的同時，分散對齊
- flex-end：靠齊右側
### align-items
用於對齊區塊 Y 軸，常用屬性值：
- center：垂直置中
- flex-end：靠齊底部

### 題目
請試著在下方程式碼 .box 中加上 flex 相關屬性讓 logo 圖片在垂直水平置中的位置，如圖：


HTML

<div class="box">
    <img src="https://raw.githubusercontent.com/hexschool/2022-web-layout-training/refs/heads/main/normal/hex-logo.png" alt="logo" width="150">
</div>

CSS

.box{
  background-color: #e8eeea;
  width: 300px;
  height: 300px;
}

> 記得加上 ==CSS Reset==
