引导导航栏响应不起作用
[英]bootstrap navbar responsive not working
问题描述
On full window screen I have the navbar exactly as I want.But once I make the window small to check if it is reponsive I do no get all the menu buttons(home,skills,aboutus,contact) one after other and secondly when I resize the window screen back to full screen the navbar becomes small. 
在全窗口屏幕上，导航栏完全符合我的需求。但是，一旦我将窗口缩小以检查其是否响应，我就不会一遍又一遍地获取所有菜单按钮（主页，技能，简介，联系方式），而当我单击时将窗口屏幕调整为全屏，导航栏会变小。

Remove the following css from your file and add one media query in it. 从文件中删除以下CSS，然后在其中添加一个媒体查询。 It will work 会工作的
Remove this 删除这个
.navbar.center .navbar-inner .nav
{
float: none;
display:inline-block;
}
Add this 加上这个
@media (max-width:544px){
.navbar-nav .nav-item
{
float: none !important;
}
}
