css – 自定义SO的片段选择背景

我目前正在尝试用Stylish创建一个黑暗的SO主题.
在我必须自定义代码段之前,一切都很顺利.
我似乎无法将选择颜色更改为除预定义之外的任何颜色：

.CodeMirror-line::selection,.CodeMirror-line>span::selection,.CodeMirror-line>span>span::selection{
    background:#d7d4f0;
}

我尝试添加这个,但没有任何改变：

.CodeMirror-line::selection,.CodeMirror-line>span>span::selection{
    background: blue !important;
}

反正有没有改变这里的选择背景？

这是主题中的完整CSS,如果它有帮助：

解决方法

在codemirror.css中,从第321行您将看到：

.CodeMirror-selected { background: #d9d9d9; }
.CodeMirror-focused .CodeMirror-selected { background: #d7d4f0; }
.CodeMirror-crosshair { cursor: crosshair; }
.CodeMirror-line::selection,.CodeMirror-line > span::selection,.CodeMirror-line > span > span::selection { background: #d7d4f0; }
.CodeMirror-line::-moz-selection,.CodeMirror-line > span::-moz-selection,.CodeMirror-line > span > span::-moz-selection { background: #d7d4f0; }

>将这些规则复制到样式表中.>尝试用所有这些规则的自定义颜色替换background-color属性.>尝试添加！重要.
