CSS怎样去除按钮之间的间距
正常情况下，当我们设置了按钮之后，按钮之间会出现间距，示例如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
</head>
<body>
<button>按钮</button>
<button>按钮</button>
<button>按钮</button>
</body>
</html>
输出结果：
这时候我们是需要设置按钮元素的父元素，给其父元素添加“font-size:0;”样式即可。
示例如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
<style>
body{
font-size:0;
}
</style>
</head>
<body>
<button>按钮</button>
<button>按钮</button>
<button>按钮</button>
</body>
</html>
输出结果：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
<style>
div{
