如果您只想要项目,请使用
.navbar-nav {
align-items: flex-end;
}
ul
设置为flex-direction: column;
,这意味着您必须使用align-items
水平放置项目,justify-content
垂直放置项目。
试试这个代码段:
.navbar-nav {
align-items: flex-end;
}
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/css/bootstrap.min.css">
<!--Navbar-->
<nav class="navbar navbar-expand-lg navbar-light bg-white ">
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNavDropdown">
<ul class="navbar-nav navbar-right mr-auto">
<li class="nav-item">
<a class="nav-link" href="#">Gmail</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Images</a>
</li>
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="http://example.com" id="navbarDropdownMenuLink" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Circle
</a>
<div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item" href="#">Something else here</a>
</div>
</li>
</ul>
</div>
</nav>

如果您希望所有内容都位于页面的右侧(汉堡包图标和项目),您可以这样做:
.navbar-nav {
align-items: flex-end;
}
nav.navbar {
justify-content: flex-end;
}
.dropdown.show, .dropdown-menu.show {
text-align: right;
}
由于nav.navbar
具有默认flex-direction: row
,justify-content
水平定位内容,align-items
垂直定位内容nav.navbar
。
我在列表项下拉列表中设置text-align: right;
,以便在打开时保持与右边对齐。
请尝试以下代码段:
.navbar-nav {
align-items: flex-end;
}
nav.navbar {
justify-content: flex-end;
}
.dropdown.show, .dropdown-menu.show {
text-align: right;
}

此代码段将确保所有内容在所有屏幕宽度上与右侧对齐。我从html中删除了mr-auto
,因为它干扰了flexbox将内容证明为Flex容器末尾的能力。
.navbar-nav {
align-items: flex-end;
}
nav.navbar {
justify-content: flex-end;
}
.dropdown.show,
.dropdown-menu.show {
text-align: right;
}
@media (min-width: 992px) {
.navbar-expand-lg .navbar-collapse {
justify-content: flex-end;
}
.dropdown-menu.show {
left: -8rem;
}
}
