文字

语法:

text-overflow:clip | ellipsis

默认值clip

适用于:块级容器元素

继承性:无

动画性:否

计算值:指定值

取值:

  • clip:当内联内容溢出块容器时,将溢出部分裁切掉。

  • ellipsis:当内联内容溢出块容器时,将溢出部分替换为(...)。

说明:

当块容器 <' overflow '> 为非visible时,定义内联内容溢出其块容器是否截断或者添加(...)及自定义字符
  • 要使得 <' text-overflow '> 属性生效,块容器必须显式定义 <' overflow '> 为非visible值,同时显式或者隐式的定义 <' width '> 为非auto值, <' white-space '> 为nowrap值。

    用代码来解释这段话:

    case 1:

    <style> .demo p{overflow:hidden;width:200px;white-space:nowrap;text-overflow:ellipsis;} </style> <div class="demo"> <p>这是一句非常非常长的话,被用来做text-overflow属性测试。</p> </div>

    case 1,我们将text-overflow生效必备的3个属性: <' overflow '> , <' width '> 和 <' white-space '> 都直接定义在了内联内容的父级块容器上

    case 2:

    <style> .demo{width:200px;white-space:nowrap;} .demo p{overflow:hidden;text-overflow:ellipsis;} </style> <div class="demo"> <p>这是一句非常非常长的话,被用来做text-overflow属性测试。</p> </div>

    case 2,我们将 <' width '> 和 <' white-space '> 定义在了更外层的块容器上,但case 1和case 2的效果是一样的。因为这2个属性可以被继承

  • 对应的脚本特性为textOverflow
