中心我在頁面中的引導形式

我有以下代碼，它不會粘在頁面的中間。我已經嘗試了很多CSS技巧來把它放到頁面的中心，但我不能。任何建議？我應該添加到CSS以便它出現在m頁的中間？中心我在頁面中的引導形式

什麼這個網站的一部分，你想爲中心？你的CSS在哪裏？ – Bek

@Amir Torkashvand：我提供了兩種解決方案。使用任何你喜歡的。 – Arif

您可以使用CSS規則做到這一點，但在這裏它是一個內聯樣式：

變化

<div class="container">

到

<div class="container" style="text-align:center">

結果：

我希望整個表單位於頁面中心style =「text-align：center」僅用於字體而不是整個表單 –

向我的anwser添加了一個圖像，我不明白你的意思，全部內容居中。請解釋一下你看起來不正確的東西 – dprogramz

BOOTSTRAP FIX：更換col-md-6 offset-md-3的form標籤上面col-xs-6 col-xs-offset-3 col-sm-6 col-sm-offset-3 col-md-6 col-md-offset-3 col-lg-5 col-lg-offset-3

NORMAL MODE：

添加float: none !important; margin: 0 auto;
