裝置：一般電腦螢幕

<!DOCTYPE html>
<html>
<head>
	<title>lab1</title>
  	<style>
      	.box{
        width: 300px;
      	height: 100px;
      	background-color: pink;
      	}
  	</style>
</head>
<body>
	<div class="box"></div>
</body>
</html>

創造一個區塊

<!--Media Queries-->
<style>
  @media screen and (min-width: 500px){
    .box{
      width: 500px;
      background-color: green;
    }
  }

  @media screen and (min-width: 1000px){
    .box{
      width: 1000px;
      background-color: blue;
    }
  }
</style>

加上 Media Queries

<!DOCTYPE html>
<html>
<head>
	<title>lab1</title>
  	<style>
      	.box{
        width: 300px;
      	height: 100px;
      	background-color: pink;
      	}
      
      @media screen and (min-width: 500px){
      .box{
        width: 500px;
        background-color: green;
      }
    }
      
      @media screen and (min-width: 1000px){
      .box{
        width: 1000px;
        background-color: blue;
      }
    }
  	</style>
</head>
<body>
	<div class="box"></div>
</body>
</html><!--Media Queries-->
