Question

我是HTML / CSS的新手，我试图创建一个带有登录下拉菜单的页面，但由于某种原因，它的右侧没有填充。我该如何解决？

我无法找到解决方案。

<div class="navbar navbar-fixed-top navbar-default">
  <div class="navbar-header"><a class="navbar-brand">My Site</a>
    <a class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">

Answer 1

正如Bootstrap文档所说，有时您需要将下拉容器放在不同的位置，对于那些需要添加dropdown-menu-right类的情况，如下所示：

 <div class="dropdown-menu dropdown-menu-right" style="padding: 10px;min-width:240px;">

这是一个JSFiddle，示例有效：

Answer 2

应更改HTML结构以反映基本Bootstrap类。 Pull-right未按照您使用它的方式受到尊重，请改用navbar-right。检查Docs以查看默认选项。

*此课程也不存在＆gt; <span class="glyphicon glyphicon-bar"></span>

请参阅工作示例摘录。

＆＃13;

.navbar .dropdown-menu-fb {
  padding: 10px;
  min-width: 240px;
}
.navbar .navbar-toggle {
  padding: 5px 10px;
}

Answer 3

容器太大而且它出了屏幕？处理最小宽度并让容器留在视口内，而不是专注于填充。

<div class="dropdown-menu" style="padding: 10px;min-width:200px;">

可能你必须使用下拉菜单来修复它，我们需要css代码

下拉容器未显示正确的填充
