如何使用Bootstrap-4将可折叠按钮菜单显示在屏幕右侧而不是左侧

navbar bootstrap-4 flexbox css html

嗨,我是网络开发新手,还在学习。我的导航栏在 flexbox 从 collapsable 屏幕左侧导航栏上打开的按钮,到目前为止,我还没有尝试任何东西使其移动。

    <nav class="navbar sticky-top navbar-expand-md navbar-dark bg-dark">   
  <a class "navbar-brand justify-content-start" href="#">
      <img src="https://pbs.twimg.com/profile_images/91427004/brule_400x400.jpg" alt="Logo" style="width: 60px;">
    </a>
    <div class="d-flex w-80 ml-auto">
      <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#collapsingNavbar">
            <span class="navbar-toggler-icon"></span>
        </button>     
    </div>
    <div class="navbar-collapse collapse" id="collapsingNavbar">
      <ul class="navbar-nav navbar-right ml-auto">

        <li class="nav-item active expandMenu">
          <a class="nav-link" href="#">Portfolio</a>
        </li>
        <li class="nav-item active expandMenu">
          <a class="nav-link" href="#">Portfolio</a>
        </li>
        <li class="nav-item active expandMenu">
          <a class="nav-link" href="#">Contact</a>
        </li>
      </ul>
    </div>
  </nav>

以下代码是CSS:

nav {
  width: 100%;
  height: 70px;
  font-size: 175%;
}

.expandMenu {

  background: rgb(52, 58, 64);
  width: 50%;
  margin-top: -5px;
  text-align: center;

}

为类指定宽度 navbar-right 至50%并移除 width 50%来自 .expandMenu

nav {
  width: 100%;
  height: 70px;
  font-size: 175%;
}

.expandMenu {
  background: rgb(52, 58, 64);
  margin-top: -5px;
  margin-left 100%;
  text-align: center;
}

.navbar-right {
  width: 50%;
}
