此代码在运行
W3C CSS Validator时触发错误：
p{
text-overflow: ellipsis;
}
我明白了：
Line Code context Error/Warning 2 p Parse Error [empty string]
它只是验证器中的一个错误,还是我错过了一些非常明显的东西？
解决方法
这是一个
bug in the CSS validator,它已经有报道. text-overflow：省略号是一个有效的规则,但遗憾的是W3C CSS验证器容易出错(见
bug list).
但请注意,当前工作草案将一些文本溢出值列为feature at risk：
The Working Group has identified the following features as at risk of being removed from CSS Basic User Interface Module Level 3 when exiting CR. Implementors are urged to implement these features,if they wish to see these features remain in this specification. All other features are either defined in a normative reference (e.g. CSS 2.1 [CSS21] or Selectors [SELECT]) or are believed to have two or more implementations,and thus will not be dropped without returning to last call.
- […]
text-overflowproperty value:<string>text-overflowproperty 2-value Syntax and definition.
虽然这不会影响省略号值,但它可能是验证器中错误的来源：
Parse Error [empty string]
