css to remove text shadow on select / highlight text (mozilla)
提问by Danield
I'm using text shadows for most text site wide, but when you highlight / select the text - the text looks fuzzy. So in order to remove the text shadow I use this css from here.
我在大多数文本站点范围内使用文本阴影，但是当您突出显示/选择文本时 - 文本看起来很模糊。所以为了删除文本阴影，我从这里使用了这个 css 。
::-moz-selection,
::-webkit-selection,
::selection {
text-shadow: none;
background: #333;
color: #fff;
}
The problem is that for some reason moz-selectiondoesn't seem to work (anymore?) in mozilla (Firefox).
问题是，出于某种原因moz-selection，在 mozilla (Firefox) 中似乎不起作用（不再？）。
Here's the jsFiddle

It seems like the problem was due to grouping multiple css rules (for the vendor specific css) together in conjuntion with the ::selection pseudo element.
问题似乎是由于将多个 css 规则（针对供应商特定的 css）与 ::selection 伪元素组合在一起。
I originally thought that it was sufficient to write each statement on a separate line.
我最初认为将每个语句写在单独的行上就足够了。
I was mistaken.
我错了。
So if I replace this code:
因此，如果我替换此代码：
::-moz-selection,
::selection {
text-shadow: none;
background: #333;
color: #fff;
}
..With this code:
..用这个代码：
::-moz-selection
{
text-shadow: none;
background: #333;
color: #fff;
}
::selection {
text-shadow: none;
background: #333;
color: #fff;
}
.... bingo, it works.
....宾果游戏，它的工作原理。
Support is also very good (for desktop): Caniuse
支持也很好（对于桌面）：Caniuse
Also, if you use LESS or SASS - you could easily write a mixin to get around the repitition.
此外，如果您使用 LESS 或 SASS - 您可以轻松编写一个 mixin 来解决重复问题。

The following is documented on Mozilla Developer Network:
以下记录在 Mozilla Developer Network 上：
Though this pseudo-element was in drafts of CSS Selectors Level 3, it was removed during the Candidate Recommendation phase, as it appeared that its behavior was under-specified, especially with nested elements, and interoperability wasn't achieved (based on discussion in the W3C Style mailing list).
The ::selection pseudo-element currently isn't in any CSS module on the standard track. It should not be used in production environments.
虽然这个伪元素在 CSS Selectors Level 3 的草案中，但它在候选推荐阶段被删除了，因为它的行为似乎没有指定，尤其是嵌套元素，并且没有实现互操作性（基于讨论W3C 风格的邮件列表）。
::selection 伪元素当前不在标准轨道上的任何 CSS 模块中。它不应该在生产环境中使用。
