最小工作範例 (MWE)

Question

大家好，新年快樂！

第一次在這裡發帖，我只是有一個快速問題，我無法解決。我使用 Metropolis 主題發布了基本 LaTeX 投影機代碼的 MWE。 * 我希望（全局）讓進度條在其周圍有一個邊框，指定邊框的顏色和厚度（假設一個 0.25pt 的藍色邊框）厚的）。如何才能做到這一點？

如果有什麼需要澄清的地方，請告訴我。先非常感謝任何好心人考慮我的問題。

希望大家2024年快樂健康！

*具體來說，背頁模板，取代了框架，並對 MWE 程式碼的第一行和序言的「我的 Mods」部分進行了少量修改。

Answer 1

進度條樣式是使用 Beamer 模板progress bar in section page和中的 TikZ 定義的progress bar in head/foot。這些模板的定義可在metropolis文件。透過將這些定義複製並貼上到 MWE 並修改 TikZ 程式碼，我能夠在進度條周圍獲得一個非常簡單的邊框（2pt 厚度，以便於查看）：
