CSS line-height用法及代码示例

CSS中的line-height属性用于设置用于行的空间量，例如文本中的空间。不允许使用负值。

用法:

line-height:normal|number|length|percentage|initial|inherit;

属性值：

正常：此模式代表法线高度。这是默认值。

line-height:normal;

例：

<!DOCTYPE html> 
<html> 
    <head> 
        <title>CSS line-height Property</title> 
        <style> 
            .geek { 
              line-height:normal; 
              background:green; 
              color:white; 
            } 
        </style> 
    </head> 
    <body style = "text-align:center;"> 
        <h1 style = "color:green;"> 
            GeeksforGeeks 
        </h1> 
          
        <h2> 
            CSS line-height Property 
        </h2> 
          
        <div class="geek"> 
            A computer science portal for geeks.<br> 
            This div has line-height:normal; 
        </div> 
    </body> 
</html>

输出：
lineheight

数：该值是一个无单位数乘以当前的font-size来设置行高。在大多数情况下，这是设置line-height并避免由于继承而导致意外结果的首选方法。

line-height:number;

例：

<!DOCTYPE html> 
<html> 
    <head> 
        <title>CSS line-height Property</title> 
        <style> 
            .geek { 
              line-height:2.5; 
              background:green; 
              color:white; 
            } 
        </style> 
    </head> 
    <body style = "text-align:center;"> 
        <h1 style = "color:green;"> 
            GeeksforGeeks 
        </h1> 
          
        <h2> 
            CSS line-height Property 
        </h2> 
          
        <div class="geek"> 
            A computer science portal for geeks.<br> 
            This div has line-height:2.5; 
        </div> 
    </body> 
</html>

输出：
lineheight

长度：在此模式下，将指定固定的行高。

line-height:length;

例：

<!DOCTYPE html> 
<html> 
    <head> 
        <title>CSS line-height Property</title> 
        <style> 
            .geek { 
              line-height:2em; 
              background:green; 
              color:white; 
            } 
        </style> 
    </head> 
    <body style = "text-align:center;"> 
        <h1 style = "color:green;"> 
            GeeksforGeeks 
        </h1> 
          
        <h2> 
            CSS line-height Property 
        </h2> 
          
        <div class="geek"> 
            A computer science portal for geeks.<br> 
            This div has line-height:2em; 
        </div> 
    </body> 
</html>

输出：
lineheight

百分比：此模式用于以当前字体大小的百分比设置行高。

line-height:percentage;

例：

<!DOCTYPE html> 
<html> 
    <head> 
        <title>CSS line-height Property</title> 
        <style> 
            .geek { 
              line-height:150%; 
              background:green; 
              color:white; 
            } 
        </style> 
    </head> 
    <body style = "text-align:center;"> 
        <h1 style = "color:green;"> 
            GeeksforGeeks 
        </h1> 
          
        <h2> 
            CSS line-height Property 
        </h2> 
          
        <div class="geek"> 
            A computer science portal for geeks.<br> 
            This div has line-height:150%; 
        </div> 
    </body> 
</html>
