我做错了什么？

编辑：
按照建议添加 col-xs-* 后，发生了奇怪的行为。 当我添加 col-xs-* 时，这些字段只适合 768 像素及以上。如果它低于 768px，它们会增长！ 完全相反！ 如何解决这个问题？
768px以下：http://postimg.org/image/d0zcna7bf/
768px 及以上：http://postimg.org/image/56isu0qtt/
【问题讨论】：
-
这不是问题。引导程序工作正常。我正在使用 ASP。网络 MVC。样式表在 BundleConfig 中声明。
-
在此处阅读网格系统getbootstrap.com/css/#grid 您可能需要使用 col-xs-*，将 * 替换为您想要的大小
