# text-overflow
**版本：CSS3**
继承性：无
### 语法：
**text-overflow** ： clip | ellipsis
### 取值：
clip：不显示省略标记（...），而是简单的裁切。ellipsis：当对象内文本溢出时显示省略标记（...）
### 说明：
1. 设置或检索是否使用一个省略标记（...）标示对象内文本的溢出。对应的脚本特性为textOverflow。
1. text-overflow属性仅是注解，当文本溢出时是否显示省略标记。并不具备其它的样式属性定义。要实现溢出时产生省略号的效果还须定义：强制文本在一行内显示（white-space:nowrap）及溢出内容为隐藏（overflow:hidden），只有这样才能实现溢出文本显示省略号的效果。
### 兼容性：
### text-overflow : clip
