方法一：使用box-pack的justify实现：使用display：flex弹性盒子模型实现根据窗口大小自适应宽度。代码如下：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<meta content="width=device-width,initial-scale=1.0,maximum-scale=1.0,user-scalable=no" name="viewport">
<style>
*{
margin: 0;
padding: 0;
}
.container{
display: -webkit-box;
display: -webkit-flex;
display: -ms-flexbox;
display: flex;
margin-top: 30px;
-webkit-box-pack: justify;
-webkit-justify-content: space-between;
-ms-flex-pack:justify ;
justify-content: space-between;
}
.container a{
width:20%;
display: block;
height: 50px;
line-height: 45px;
text-align: center;
border 1px solid red;
color: sandybrown;
font-size: 16px;
margin-bottom: 5px;
border-radius: 3px;
background-color: skyblue;
text-decoration: none;
}
</style>
</head>
<body>
<p class="container">
<a class="link" href="#">10</a>
<a class="link" href="#">20</a>
<a class="link" href="#">30</a>
<a class="link" href="#">50</a>
</p>
</body>
</html>效果如下：
方法二：使用column多列 布局实现，具体代码如下：

-webkit-column-gap: 20px;-moz-column-gap: 20px;column-gap: 20px;
margin-top: 100px;
}
.container a{
display: block;
height: 50px;
line-height: 50px;
text-align: center;
border: 1px solid sandybrown;
color: #0066CC;
font-size: 16px;
margin-bottom: 5px;
border-radius: 4px;
background-color: salmon;
text-decoration: none;
}
</style>
</head>
<body>
<p class="container">
<a class="link" href="#none">10元</a>
<a class="link" href="#none">20元</a>
<a class="link" href="#none">30元</a>
<a class="link" href="#none">50元</a>
</p>
</body>
</html>效果如下：
