使用新属性的有效CSS [英] Valid CSS with new properties

问题描述

我使用一些CSS技巧来提高我的网站在Webkit浏览器的可用性/外观。两个主要的是 text-shadow 和 resize：none （在textareas-停止恼人的分页调整大小选项在Safari和其他）。

I am using a few CSS tricks to boost up the usability/appearance of my site in Webkit browsers. The two main ones are text-shadow and resize:none (on textareas - to stop that annoying page-breaking resize option in Safari and others).

问题是，当我通过W3验证器运行我的页面我得到吨：

The problem is that when I run my page through the W3 validator I get tons of:

属性text-shadow在CSS级别2.1中不存在，但存在于：＃feb4b4 1px 1px 0＃feb4b4 1px 1px 0

Property text-shadow doesn't exist in CSS level 2.1 but exists in : #feb4b4 1px 1px 0 #feb4b4 1px 1px 0

和 -

CSS级别2.1中不存在属性调整大小， none none

Property resize doesn't exist in CSS level 2.1 but exists in : none none

这真的无效吗？

推荐答案

text- shadow 属性是一个CSS3属性。如果你从W3 CSS Validator服务的高级选项中选择CSS级别3，它应该通过okay。它也在CSS级别2，但是对于CSS级别2.1。

The text-shadow property is a CSS3 property. If you pick CSS Level 3 from the advanced options on the W3 CSS Validtor service, it should come through okay. It was also in CSS Level 2, but dropped for CSS Level 2.1.
