HTML Style textOverflow用法及代码示例

HTML DOM中的Style textOverflow属性用于指定文本在包含元素框溢出时的行为。

用法:

它返回textOverflow属性。
```
object.style.textOverflow
```

它用于设置textOverflow属性。

object.style.textOverflow = "clip|ellipsis|initial|inherit"

属性值：

clip:如果内容溢出，则用于剪辑内容。它是默认值。

例：

<!DOCTYPE html> 
<html> 
      
<head> 
    <title> 
        DOM Style textOverflow Property 
    </title> 
      
    <style> 
        .content { 
            background-color:lightgreen; 
            height:100px; 
            width:300px; 
            white-space:nowrap; 
            overflow:hidden; 
            text-overflow:ellipsis; 
        } 
    </style> 
</head> 
  
<body> 
    <h1 style="color:green"> 
        GeeksforGeeks 
    </h1> 
      
    <b>DOM Style textOverflow Property</b> 
      
    <p> 
        The textOverflow property specifies how text 
        should be displayed when it overflows the  
        container element. 
    </p> 
      
    <div class="content"> 
        GeeksforGeeks is a computer science portal with 
        a huge variety of well written <br>explained  
        computer science and programming articles,  
        quizzes and interview questions. <br>The portal
