我有以下代码,它不会粘在页面中间。我尝试了很多CSS技巧,让它到达页面的中心,但我不能。有什么建议吗?我应该将什么添加到CSS中,以便它出现在m页的中间?

您可以使用CSS规则执行此操作,但此处它是内联样式:
更改
<div class="container">
到
<div class="container" style="text-align:center">
结果:

BOOTSTRAP FIX :
使用col-md-6 offset-md-3
form
标记上方的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
正常模式:
添加float: none !important; margin: 0 auto;
