Question

我正在玩Bootstrap 4，更具体地说是导航栏菜单。有没有办法让小导航栏切换按钮对齐到页面右侧，而不是让它浮动到徽标旁边的左侧？

这是我目前的代码。

＆＃13;

@media (min-width: 992px) {
    .navbar-nav li a { line-height: 85px; }
}

@media (max-width: 991px) {
    .navbar-brand { float: none; }
}

.navbar-toggler{
    border:none;
    width:1em;
}

＆＃13;

 <nav class="navbar navbar-light bg-faded navbar-full">
          <a class="navbar-brand" href="#"><img class="img-fluid" src="img/logoMedium.png" /></a>
          <button class="navbar-toggler hidden-lg-up" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation"></button>
          <div class="collapse navbar-toggleable-md" id="navbarResponsive">
              <ul class="nav navbar-nav">
                  <li class="nav-item active">
                      <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
                  </li>
                  <li class="nav-item">
                      <a class="nav-link" href="#">About Us</a>
                  </li>
                  <li class="nav-item">
                      <a class="nav-link" href="#">Solar Power</a>
                  </li>
                  <li class="nav-item">
                      <a class="nav-link" href="#">No Obligation Quote</a>
                  </li>
                  <li class="nav-item">
                      <a class="nav-link" href="#">Contact Us</a>
                  </li>
              </ul>
          </div>
      </nav>

＆＃13;

感谢您的帮助：）

Answer 1

只需将班级ml-auto添加到切换按钮即可以这种方式你做左边缘：自动

<button type="button" class="navbar-toggler ml-auto hidden-sm-up float-xs-right" data-toggle="collapse" data-target="#navbarResponsive" aria-expanded="false" aria-label="Toggle navigation"></button>

Answer 2

使用.float-xs-right类：

<button class="navbar-toggler hidden-lg-up float-xs-right" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation"></button>

或者将float: right;添加到.navbar-toggler，如下面的代码段所示：

Note that pull-right has been removed in v4.

＆＃13;

@media (min-width: 992px) {
  .navbar-nav li a {
    line-height: 85px;
  }
}
@media (max-width: 991px) {
  .navbar-brand {
    float: none;
  }
}
.navbar-toggler {
  border: none;
  width: 1em;
  float: right;
}

Answer 3

将课程向右拉，您将获得您正在寻找的结果。

<button class="navbar-toggler hidden-lg-up pull-right" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation"></button>

或者您可以使用以下参数定义样式：

float: right !important;

Answer 4

这就是我解决这个问题的方法：

<header>
    <nav class="navbar navbar-fixed-top navbar-dark bg-inverse">
        <a class="navbar-brand" href="#">Fixed top</a>
        <button type="button" class="navbar-toggler hidden-sm-up float-xs-right" data-toggle="collapse" data-target="#navbarResponsive" aria-expanded="false" aria-label="Toggle navigation"></button>
        <div class="clearfix"></div>
        <div class="collapse navbar-toggleable-xs" id="navbarResponsive">
            <ul class="nav navbar-nav">
                <li class="nav-item active">
                    <a href="#" class="nav-link">Home<span class="sr-only">(current)</span></a>
                </li>
                <li class="nav-item">
                    <a href="#" class="nav-link">Planets</a>
                </li>
                <li class="nav-item">
                    <a href="" class="nav-link">Spaceships</a>
                </li>
                <li class="nav-item">
                    <a href="" class="nav-link">About</a>
                </li>
                <li class="nav-item">
                    <a href="" class="nav-link">Contact</a>
                </li>
            </ul>
        </div>
    </nav>
</header>

请注意，您必须使用clearfix，因为否则按钮中的浮动会在菜单崩溃时对菜单执行时髦的操作。

Answer 5

这对我在Bootstrap 4中起作用

<button type="button" class="navbar-toggler navbar-toggler-right"
        data-toggle="collapse" data-target=".navbar-collapse"
        aria-controls="navbar-collapse" aria-expanded="false" aria-label="Toggle navigation">

甚至更简单来自Bootstrap docs

<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>

Answer 6

＆＃13;

 .navbar-light .navbar-nav .nav-link {
    color: rgb(255, 255, 255) !important;
}
.navbar {
    
    display: block !important;
        min-height: 54px;
    }
    .pull-right{
    float:right !important;
    }

Answer 7

您必须像另一个按钮标签一样对齐它，首先将其包装在容器中以便以后移动。之后，使用.text-right类创建一个div，然后将切换按钮放入其中。请参见下面的示例。

<div class='container'>
   <div class='text-right'>
      <button> Button1 </button>
   </div>    
</div>

或

<div class='container text-right'>       
   <button> Button1 </button>       
</div>enter code here

这两个解决方案在Bootstrap 4.5中都可以完美运行

Answer 8

只需使用import numpy as np real = np.ones((2, 3)) imag = 2*np.ones((2, 3)) complex = np.vectorize(complex)(real, imag) # OR complex = real + 1j*imag，您的问题就可以解决。

它应该像这样：

navbar-expand-lg

将导航栏切换按钮对齐到右侧
