【问题描述】：

这是我的 mvc 局部视图：

<nav class="navbar navbar-inverse navbar-fixed-top">
        <div class="container-fluid">
            <div class="navbar-header">
                <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar">
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                </button>
                @Html.RouteLink("მთავარი", "AdminControlUsers", null, new { @class = "navbar-brand", @style="padding-left:100px; padding-right:100px"})//this line
            </div>
    <div class="collapse navbar-collapse" id="myNavbar">
                <ul class="nav navbar-nav">
                    @if (ViewBag.NavBarActive == "მომხმარებლები")
                    {
                        <li class="active">@Html.RouteLink("მომხმარებლები", "AdminControlUsers")</li>
                        <li>@Html.RouteLink("Stored Procedures", "ControlStoredProcedures", new { page = 1 })</li>
                        <li>@Html.RouteLink("გაშვებული Stored Procedure-ები", "Admin_User_Results_List")</li>
                    }
                    @if (ViewBag.NavBarActive == "Stored Procedures")
                    {
                        <li>@Html.RouteLink("მომხმარებლები", "AdminControlUsers")</li>
                        <li class="active">@Html.RouteLink("Stored Procedures", "ControlStoredProcedures", new { page = 1 })</li>
                        <li>@Html.RouteLink("გაშვებული Stored Procedure-ები", "Admin_User_Results_List")</li>
                    }
                    @if (ViewBag.NavBarActive == "User_Admin Results List")
                    {
                        <li>@Html.RouteLink("მომხმარებლები", "AdminControlUsers")</li>
                        <li>@Html.RouteLink("Stored Procedures", "ControlStoredProcedures", new { page = 1 })</li>
                        <li class="active">@Html.RouteLink("გაშვებული Stored Procedure-ები", "Admin_User_Results_List")</li>
                    }
                </ul>
                <ul class="nav navbar-nav navbar-right">
    li><a href='@Url.Action("LogOut", "Administrator")'><span class="glyphicon glyphicon-log-out"></span> გამოსვლა @Session["Admin"].ToString()</a></li>
                </ul>
            </div>
        </div>
    </nav>

当我调整浏览器的大小时，我的导航栏截图：

当我删除其中一行时：

@Html.RouteLink("მთავარი", "AdminControlUsers", null, new { @class = "navbar-brand", @style="padding-left:100px; padding-right:100px"})

如果我删除 @style="padding-left:100px; padding-right:100px" 它可以正常工作：/。请帮忙

【问题讨论】：

您到底想达到什么目的？第三张图片折叠按钮按预期激活，在第二张图片上，您的内容溢出被向上推，您不希望导航栏折叠吗？或者您希望它比溢出发生时更快地崩溃？
是的@Syden。我想要折叠，不要像第二张和第三张图片那样得到导航栏

【解决方案1】：

内容溢出早于折叠button，您需要将导航栏折叠按钮设置为更早显示。

您可以通过 CSS 来实现，在样式表中将其设置在最后（根据您的需要调整 min-width 和 max-width）：

@media (min-width: 768px) and (max-width: 991px) {
    .navbar-collapse.collapse {
        display: none !important;
    }
    .navbar-collapse.collapse.in {
        display: block !important;
    }
    .navbar-header .collapse, .navbar-toggle {
        display:block !important;
    }
    .navbar-header {
        float:none;
    }
}

【讨论】：

感谢@Syden，但是当我现在调整浏览器大小时会显示按钮，但也有其他选项
对不起，我没有关注，选项是你分享的，我不知道其他选项可能与否。无论您想在折叠button 中放置什么，都将它放在<div class="collapse navbar-collapse" id="myNavbar">option</div> 中。剩下的任何东西都将是可见的。

我探索了这一行：@Html.RouteLink("მთავარი", "AdminControlUsers", null, new { @class= "navbar-brand", @style="padding-left:100px; padding-right:100px"})
还有这个：@style="padding-left:100px; padding-right:100px"
在这段代码中，如果没有 @style 元素，你添加的答案就是我的
我从不使用 MVC Web。对此感到抱歉。您可以使用 javascript 来为此添加类和 CSS 样式。
