使用 Macbuntu-O shell 主题时顶部栏上的阴影效果

Question

这是我在此的头一篇博文。

我运行的是 Ubuntu 18.04，并且最近安装了可用的 MacBuntu 主题包。

看起来很棒，唯一的问题是——我想知道是否有人知道如何去除使用 MacBuntu-O shell 主题时顶部栏上的文本和图标的阴影效果？

是否有人知道在相关 gnome-shell.css 文件中要编辑的相关代码部分？

PS——无论使用什么字体，都会产生阴影效果。

编辑：根据要求，我认为 gnome-shell.css 文件中代码的相关部分是：

Answer 1

只是一个解决方法..

在第 696、775 行编辑以下内容
text-shadow: none

#panel {
    background-gradient-direction:none;
    background-color: rgba(255,255,255,0.75);
/*    background-color: rgba(46,51,56,0.9);
    border:1px solid rgba(200,200,200,.5);*/
    box-shadow: 0px 1px 3px 1px rgba(0,0,0,0.5);
    border: 0px solid rgba(90,105,111,0.5);
 /*    box-shadow: 0px 0px 0px 1px rgba(0,0,0,0.15);*/
    border-top:0px;border-right:0px;border-left:0px;
    font-weight: bold;
    height: 26px;
    text-shadow: none; } #696

.panel-button {
    -natural-hpadding: 6px;/*jarak item2 panel def 12px*/
    -minimum-hpadding: 4px;
    font-weight: normal;
    color: #333;/*tulisan toolbar scr umum*/
    transition-duration: 200ms;/*nonstatus*/
    text-shadow: none; } #775

#panel.solid .panel-button { text-shadow: none; } #777

在第 777 行添加以下行
#panel.solid .panel-button { text-shadow: none; }

在第 859, 2097 行编辑以下内容
icon-shadow: none;

.system-status-icon {
    icon-size: 1.09em;
    padding: 0 4px;
    icon-shadow: none; #859
}

.popup-menu-arrow {
  width: 16px;
  height: 16px; 
  icon-shadow: none; } #2097

Answer 2

非常感谢@Mogli！

正如你们所看到的，@Mogli 的回答很有效：

我没有考虑的是系统状态图标和弹出菜单箭头部分。

与以前不同的字体也只是因为我决定也改变它（就在 .css 文件的开头）——不是“类似 helvetica”外观的忠实粉丝。

不过，我只想告诉你们，在处理这些东西时一定要小心谨慎，有一次我确实搞砸了一点（真的不知道是什么），Ubuntu 无法启动！不得不以恢复模式启动以恢复 gnome-shell.css 文件。事件发生之前出现了“配置更改 - 需要重新启动消息”（尽管你确实经常收到这些消息，并且它会顺利重新启动）。

再次感谢@Mogli 的一切努力！
