问题是我正在开发一个应用程序，并且在主屏幕上有一个菜单，该菜单由bootstrap4 navbar制成，从VS2017（iis expres）的navbar运行该应用程序，它显示正确，如何在下面显示图片：

要让客户端访问，请查看进度并提出意见，我将应用程序放置在IIS Web服务器上，以供以后访问，发现该服务器本身（Windows Server 2012）和工作站中的导航栏是显示不正确，显示如下：
NavBar shown when opening the application from iis in windows server 2012
如您所见，导航栏的许多详细信息在Windows Server 2012 IIS中丢失。
我想表达您的宝贵意见，以查看是否有可能解决此问题，任何信息，代码部分或任何需要帮助的信息，请告诉我。
预先感谢和问候。
