如何在Bootstrap导航栏中设置汉堡菜单中的项目样式

Question

我用Bootstrap4创建了一个响应导航栏。当屏幕很大时，有两个按钮。当屏幕很小的时候，就会有汉堡包菜单。

[在此处输入图像描述][1][在此处键入图像描述][2]

我如何在导航栏中设置元素的样式，使它们在汉堡菜单中看起来不再像按钮？

谢谢！

这是我的代码：

<a class="navbar-brand" href="index.html">MyJobBoard</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarTogglerDemo02" aria-controls="navbarTogglerDemo02" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarTogglerDemo02">
<ul class="navbar-nav navbar-right ml-auto mt-2 mt-lg-0 float-right text-right">
<li class="nav-item active">
<a class="nav-link post-a-job-button pull-right">Create a profile</a>
</li>
<li class="nav-item">
<button type="button" class="btn btn-light mr-3 pull-right">Sign In</button>
</li>
<li class="nav-item">
<button type="button" class="btn btn-primary mr-3 pull-right">Post a Job</button>
</li>
</ul>
</div>
</nav> ```

一个解决方案是将所有导航项目构建为链接，这样在较小的屏幕上，您将拥有正常的Bootstrap向下滑动菜单，然后是应用于较大显示器的自定义按钮类。

如果你的登录和离职后表格在一个单独的页面上，那么你可以使用到另一个页面的直接链接，但如果你使用模态来显示表格，那么你需要使用JavaScript来打开模态。

我在下面的例子中禁用了post-a-job按钮，这样你就可以看到如何禁用按钮，这样没有登录的人就不能发布作业了。

$('a[href$="#signInModal"]').on("click", function() {
$("#signInModal").modal('show');
});
$('a[href$="#postJobModal"]').on("click", function() {
$("#postJobModal").modal('show');
});
