我不是投影仪方面的专家，在网上搜索了几个小时之后还是找不到如何做我想做的事情，所以我寻求帮助。
我想使用 PaloAlto 主题创建一个投影仪并进行一些定制。
首先，我想将框架标题背景从我的颜色（在徽标角落）改为白色（在右侧）。我找到了几个想要类似东西的人，并尝试了他们提供的解决方案，但似乎没有什么能解决我的问题。
其次，我想对垂直侧边栏（从徽标角落）执行相同的操作，使其变为白色（底部）。
最后，我还希望标题背景不要出现在标题页上，并且标题栏稍微向上移动。
在此先感谢您的帮助！

答案1
呸，一道题有这么多问题！
1）为了给标题添加阴影，我必须重新定义标题，并用\rule水平阴影替换通常提供背景颜色的
2）给侧边栏添加阴影稍微容易一些，我只需要用sidebar canvas left垂直阴影替换模板即可
3) 框架选项是否plain满足您的要求？
