我希望定理/定義/等標籤出現在外頁邊距（考慮偶數頁和奇數頁）。首先，我嘗試使用該thmtools包（下面的程式碼和圖像）。然而，我只能設法將標籤始終放置在左邊距中。特別是，我不知道如何thmtools與ifoddpage.
接下來，我嘗試了ntheorem（下面的程式碼和圖像）。使用 時ntheorem，標籤放置可以正常工作，但我無法更改定理標題的字體樣式（下圖中的“一些重要定理”）並將其放置在自己的一行上。此外，我無法擺脫縮排。最後，它也破壞了我的autoref參考資料。
到總結：我正在尋找的是一個允許的定理環境
- 標籤在外頁邊距（奇數頁/偶數頁）
- 標籤、標題和正文的完整樣式控制
autoref相容性（特別是，我想對不同的定理環境（例如定理、定義等）使用單一計數器）
我快要放棄了，所以我真的希望有人能幫助我。
