CSS 验证未验证
/* ** ** custom select color ** ** */
::selection {
background: #525252; /* Safari */
}
::-moz-selection {
background: #525252; /* Firefox */
color:#fff;
}
上面的代码没有通过W3C验证器，但我无法理解其原因。
返回以下错误：
伪元素::selection不能 出现在上下文 css21 中 [选择]
伪元素 ::-moz-selection 不能出现在此处 上下文 css21 [-moz-selection]
/* ** ** custom select color ** ** */
::selection {
background: #525252; /* Safari */
}
::-moz-selection {
background: #525252; /* Firefox */
color:#fff;
}
The above code is not passing the W3C validator, but I can't understand the reason for it.
The following error is returned:
The pseudo-element ::selection can't
appear here in the context css21
[selection]The pseudo-element
::-moz-selection can't appear here in
the context css21 [-moz-selection]

没什么好担心的，第一个是抱怨，因为它正在针对 CSS2.1 进行测试，第二个，正如 Kyle 所建议的，是因为 -moz 前缀
要消除第一个“错误”，请执行以下操作：
单击更多选项链接并将配置文件更改为 CSS 3。
这不能消除第二个错误，并且可能应该学会忽略此类错误。我知道这听起来很痛苦，除非有人可以提供替代建议？
That's nothing to worry about, the first one is complaining because it's being tested against CSS2.1, and the second, as Kyle suggested, is because of the -moz prefix
To silence the first "error", do the following:
Click on the more options link and change the profile to CSS 3.
This can not silence the second error, and should probably learn to ignore this kind of errors. I know it sounds a big of a pain, unless anyone can offer an alternative suggestion?
即使在 CSS 级别 3 下，Mozilla/Webkit 特定的 CSS 元素也不会验证。
Mozilla/Webkit specific CSS elements do not validate even under CSS level 3.
今天，即使是 ::selection 也会出现问题，因为它已从 CSS3 中删除。
Today you have a problem even with ::selection because it was dropped from CSS3.
