CSS border-spacing属性用法及代码示例


border-spacing属性用于设置表格中相邻单元格的边界之间的距离。仅当border-collapse属性单独设置为no-collapse时，此属性才有效。

用法:

border-spacing:length|initial|inherit;

属性值：

  1. length-length:它用于设置基准单元边界之间的距离。它不允许负值。
    • 如果定义了两个值，则第一个值定义水平空间，第二个值定义垂直间距。
    • 如果仅给出一个值，则它定义单元格相邻边界之间的水平和垂直间距。

    用法:

    border-spacing:length-length;

    示例1：



    <!DOCTYPE html> 
<html> 
  
<head> 
    <title>border-spacing property</title> 
    <style> 
        table, 
        th, 
        td { 
            border:2px solid green; 
            text-align:center; 
        } 
          
        #geeks { 
            border-collapse:separate; 
            background-color:none; 
            border-spacing:20px 40px; 
        } 
          
        h1 { 
            color:green; 
        } 
    </style> 
</head> 
  
<body> 
    <center> 
        <h1>GeeksforGeeks</h1> 
        <h2> The border-spacing Property</h2> 
        <h3>border-spacing:20px 40px;</h3> 
        <table style="width:70%" id="geeks">

                <td>28</td> 
            </tr> 
        </table> 
    </center> 
</body>
