Bootstrap 3導航欄不會切換到「移動」版本

我試圖在Laravel Project中使用Bootstrap導航欄作爲頁面標題，而我正面臨着這個問題：如果我在桌面瀏覽器（Chrome， Firefox和IE）當頁面寬度變得低於768像素時伸展頁面我看到「摺疊」按鈕，我的標題在「移動」版本中正常工作，但是當我在Chrome上切換移動視圖或當我測試頁面時它向我展示了「桌面」版本的移動設備。 Bootstrap 3導航欄不會切換到「移動」版本

你嘗試定義''在''中？ – Banzay

@Banzay非常感謝你，我不知道爲什麼我刪除了元標記...如果你想寫ot作爲答案，我會接受它... – SamDroid

有一個在引導文檔的基本模板指令：

複製下面的HTML開始與最小的引導文件的工作：

<!DOCTYPE html> 
<html lang="en"> 
    <head> 
    <meta charset="utf-8"> 
    <meta http-equiv="X-UA-Compatible" content="IE=edge"> 
    <meta name="viewport" content="width=device-width, initial-scale=1"> 
    <!-- The above 3 meta tags *must* come first in the head; any other head content must come *after* these tags -->
