子比评论区设置私密评论

迭代版本：

• 2024.09.25：第一版
• 2024.09.26：第二版
• 2024.10.01：第三版
• 2024.10.02：第四版

魔改改进：

1. 复选框和文字间增加一段距离
2. 设置私密等与原主题保持一致
3. 设置复选框与主题保持一致
4. 将设置私密按钮移动到下拉工具栏中
5. 优化设置私密评论逻辑

代码修改：

CSS代码

在后台主题设置[自定义CSS样式]添加下面CSS代码：

/*设置私密复选框样式*/
#is-private-checkbox::before {
    transition: transform 0.2s ease;
}

#is-private-checkbox:checked::before {
    transform: translateY(-50%) translateX(-5%) scale(0.5);
}

#is-private-checkbox:not(:checked)::before {
    transform: translateY(0) translateX(0) scale(1);
}
