CSS中的line-height屬性用於設置用於行的空間量，例如文本中的空間。不允許使用負值。

正常：此模式代表法線高度。這是默認值。

line-height:normal;

<!DOCTYPE html> 
<html> 
    <head> 
        <title>CSS line-height Property</title> 
        <style> 
            .geek { 
              line-height:normal; 
              background:green; 
              color:white; 
            }

            This div has line-height:normal; 
        </div> 
    </body> 
</html>

lineheight

數：該值是一個無單位數乘以當前的font-size來設置行高。在大多數情況下，這是設置line-height並避免由於繼承而導致意外結果的首選方法。

    <body style = "text-align:center;"> 
        <h1 style = "color:green;">

        </h2> 
          
        <div class="geek"> 
            A computer science portal for geeks.<br> 
            This div has line-height:2.5; 
        </div> 
    </body> 
</html>
