我的 CSS 樣式表不再起作用/連結到我的 HTML 文件 - 可能是什麼原因?

我已經在很多論壇上搜索了答案,並且查看了大約 50 個 google 鏈接,但還沒有發現任何有效的方法...

我的 CSS 沒有顯示在我的 HTML 上。

我的程式碼運作得很好,直到我在其中添加了一個 Flexbox 容器和 2 個 Flexbox。

我總是測試我的程式碼,這樣我就知道 Flexbox 可以在這個特定的 HTML 檔案之外運作。

此外,我注意到我的 CSS 未在 localhost/#my_file# 上的「檢查元素」上更新。 這種情況過去已經發生過,我透過更改文件位置並將其再次更改為舊位置來解決該問題。 (我不知道rhat是如何運作的)。

無論如何,如果我將 CSS 更新表複製並貼上到「檢查元素」頁面上,我就可以很好地查看我的 Flexbox。

所以我懷疑這是因為我的 CSS 中的錯誤,但我不太確定,所以我什至檢查了它:https://jigsaw.w3.org/css-validator/#validate_by_input

只有 1 個錯誤,但我在整個 CSS 檔案中檢查了它,1) 我找不到它 2) 我刪除了所有看起來最像該錯誤的內容,但仍然不起作用。

顯然,我認為這與錯誤無關,因為它在“檢查元素”方面工作得很好。

我也知道我會犯注意錯誤,愚蠢的錯誤,所以......你知道。

我目前正在學習,如果您在我的程式碼中發現任何錯誤,請告訴我!
