# 🏅 Day 24 - mixin

mixin 是 SCSS 中的一個實用功能，能夠將你經常撰寫的重複區塊包裝起來，在需要的地方直接引入，簡化整體程式碼。

### 題目

只需更換 SCSS 內「...」的程式碼，利用 mixin 搭配 include 的方法讓上方的 CSS 換一個寫法，省去重複寫 @media 的問題。

**CSS**

.header{
  width: 500px;
}

@media(max-width: 768px){
  .header{
	width: 13px;
	font-size: 20px;
  }
}

@media(max-width: 568px){
  .header{
	font-size: 8px;
  }
}

.header a{
  background: black;
}

@media(max-width: 568px){
  .header a{
	background: white;
  }
}

**SCSS**

@mixin pad{
  @media(max-width: 768px){
	@content;
  }
}

@mixin mobile{
  @media(max-width: 568px){
	@content;
  }
}

.header{
  ...
  
  a{
     ...
  }
}
