我目前正在使用 Bootstrap 建立登陸頁面進行練習。但是,我面臨佈局問題,容器不適合適當的螢幕尺寸。左右兩側不平衡,導致螢幕向左側傾斜。
這是說明問題的螢幕截圖(連結):文字
我嘗試了各種方法,但未能解決問題。我懷疑這可能是 Bootstrap 中網格系統或容器設定的問題。
有人可以指導我如何排查和修復此佈局問題嗎?任何建議或見解將不勝感激。

我也檢查了容器語法、邊距和填充。但我實在不明白這有什麼問題..
我真的很感謝你的幫助,這對我這個新手有很大幫助。
提前致謝! !
檢查容器的位置。在程式碼片段中,您將容器類別與
col-xxl-8
類別一起使用。確保容器包裹了要居中的整個內容,並且正確地應用了 col-xxl-8 類別。並且認為您應該像這樣檢查功能部分的所有容器類別
col-12 col-sm-8 col-lg-6
用於映像容器,col-lg-6
用於文字容器。出現水平捲軸是因為功能部分溢出了正文超過 100%。新增Bootstrap類別
mw-100
,相當於在CSS中設定max-width: 100%;
。請參閱下面的程式碼片段。
