当Firefox失去焦点时，选择将更改颜色 [英] Selection changes color when Firefox loses focus

问题描述

我通过CSS设置选择背景颜色：

  :: selection {
 background：＃cc0000 ; 
 color：#fff; 
} 
 
 ::  -  moz-selection {
 background：＃cc0000; 
 color：#fff; 
} 
  

在大多数浏览器上，当焦点在其他地方选择颜色将保持不变，例如：

，但在Firefox上不会：

您可以在jsFiddle 此处。

如何让Firefox设置选择颜色在这种情况下？

解决方案

如何在这种情况下让Firefox设置选择颜色？

不幸的是，似乎没有办法。

没有人（包括Mozilla本身）可以肯定地说;这从未指定，而 :: selection 仍然在CSS3规范。我找不到有关 MDN 或错误报告的任何信息 bugzilla.mozilla.org 。但我发现此错误报告自2010年报告以来显然没有解决。

这可以在将来澄清，例如如果 :: selection 在UI 4中返回。

I'm setting the selection background color via CSS:

::selection {
  background:#cc0000;
  color:#fff;
}

::-moz-selection {
  background:#cc0000;
  color:#fff;
}

On most browsers when the focus is somewhere else (like an IFrame), the selection color will stay the same, e.g.:

but on Firefox it won't:

You can see this in action on jsFiddle here.

How can I get Firefox to set the selection color in this case? Is this a bug?

解决方案

How can I get Firefox to set the selection color in this case?

Unfortunately, there doesn't appear to be a way to do so.

Is this a bug?

Nobody (including Mozilla themselves?) can say for sure; this was never specified while ::selection was still in the CSS3 spec. I can't find any information on MDN or bug reports on bugzilla.mozilla.org on this either. but I did find this bug report, which has apparently been left unresolved since being reported in 2010.

This may be clarified in the future, e.g. if ::selection returns in UI 4.
