使用CSS在两行之间设置边框
使用带有double值的 border-style属性可以设置两行边框。您可以尝试运行以下代码以实现border-style属性:
示例
<html>
<head>
</head>
<body>
<p style = "border-width:4px; border-style:none;">
This is a border with none width.
</p>
<p style = "border-width:4px; border-style:double;">
This is a border with two solid lines.
</p>
</body>
</html>
