除了我需要最后两个导航栏元素最右对齐之外，我已经获得了以下代码以使其看起来像我想要的那样。
我可以用 ul {text-align: right;宽度:100%； background-color: #48C2C5;，但是当我这样做时，它会改变我的下拉菜单的大小。
我附上了一些图片和代码。
我在 Springshare Libguides 中这样做。
没有最右边的导航栏 2 右对齐:
截断下拉菜单:

最佳答案
我知道 LibGuides 使用 Bootstrap 3，所以我放置了一个 pull-right 类，而不是最后两个列表项上的 float right。我还将 UL 元素设置为拉伸(stretch)到 100%。下面的答案只包括 HTML，不包括 CSS，但请尝试一下:
<div id="header-abc">
<div class="container-fluid" id="banner-abc">
<div class="row">
<div class="col-sm-6 center" id="col1">
<div class="row">
<div class="col-md-6" id="logo-abc">
