我正在網頁頂部使用引導程序導航欄。與許多Bootstrap導航欄非常相似，當頁面達到一定長度時，這個特定頁面崩潰，所有標題都會進入頁面右上角的按鈕。問題是，單擊按鈕時，導航欄不顯示標題。HTML/CSS：引導程序導航欄不響應
這裏有一個問題：特別是在這一頁上，只有這一頁，欄不起作用。事實上，按鈕似乎變灰了。
（我將提供圖像，但＃1並不讓我的地方鏈接，因爲我是新用戶）
我試圖從這個頁面其它頁面替換導航欄 - 不工作。
和
我試圖從其他頁面替換該導航欄用導航欄 - 工作完全正常。
這讓我相信在這個頁面上還有其他的東西會導致Navbar被「禁用」，或者導致它不被顯示，比如缺少標籤。我已經完成了我的代碼的搜索並找不到它。
正如我之前所說的，問題在於，它只在特定的一頁上;沒有其他人。鑑於有人願意通過我的源代碼進行搜索，我已經在下面提供了一些源代碼來查找語法錯誤。
另外，請注意，我在我的代碼中添加了一個燈箱照片庫，並且已將外部鏈接和腳本放在底部。

你調用在頭2個不同的引導CSS版本和你有兩個jQuery的頁腳調用。開始刪除額外的東西，看看會發生什麼。 – vanburen
