我不是投影機的專家，在網路上待了幾個小時後，沒有找到如何做我想要的事情，我正在尋求幫助。
我想使用 PaloAlto 主題創建一個投影機並進行一些自訂。
首先，我想將框架標題背景從我的顏色（在徽標角落）變為白色（在右側）。我找到了一些想要類似東西的人，並嘗試了他們給出的解決方案，但似乎沒有什麼對我有用。
其次，我想對垂直側邊欄（從標誌角落）到白色（底部）執行相同的操作。
最後，我還希望標題背景不要出現在標題頁上，並且標題列向上移動一點。
先感謝您的幫忙！

答案1
噗，一個問題這麼多問題！
1）為了在標題中添加陰影，我必須重新定義標題並替換\rule，它通常透過水平陰影提供背景顏色
2）在側邊欄加陰影要容易一些，我只需用sidebar canvas left垂直陰影替換模板即可
3) 框架選項plain足夠您使用嗎？
