示例
下面是一个示例，其中可以将所有不同的值传递给 padding-top 属性:
<!DOCTYPE html>
<html>
<head>
<title>CSS: Padding: padding-top</title>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body>
<h3>padding-top property</h3>
<div>
<p style="padding-top: 50px; border: 1px solid #0b0b0b;">This element has a top padding of 50px.</p>
<p style="padding-top: 10%; border: 1px solid #0b0b0b;">This element has a top padding of 10%.</p>
<p style="padding-top: 30pt; border: 1px solid #0b0b0b;">This element has a top padding of 30pt.</p>
</div>
</body>
</html> inherit - 当您希望子元素的顶部填充与其父元素的顶部填充相匹配时，请使用属性继承。
注意:继承值只能在子元素上使用，不能在父元素上使用。
这是一个子元素的 padding-top 继承自父元素的示例 -
<!DOCTYPE html>

<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">

}
.box {

}
</style>
</head>
<body>
<h4>padding-top property: inherit</h4>
