html - 如何让我的 anchor 标签移动到导航栏的右侧？

Question

我有使用 Bootstrap 导航栏的以下代码。但我想让 anchor 标签在笔记本电脑上全屏显示时移动到右侧。我怎么做？如果可以的话，请也显示 CSS。谢谢!

<nav class="navbar navbar-expand-lg navbar-light bg-light">
                  <a class="navbar-brand" href="#">J & M Residential Cleaning Services</a>
                  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
                    <span class="navbar-toggler-icon"></span>
                  </button>
                    <div class="collapse navbar-collapse" id="navbarNav">
                        <ul class="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="#">Book Online</a>
                          </li>
                          <li class="nav-item">
                            <a class="nav-link" href="#">Contact Us</a>
                          </li>
                        </ul>
                    </div>
            </nav>

要将文本在下拉列表中向右对齐，请设置 text-align: right 在 .navbar-collapse 上:

.collapse.navbar-collapse {
  align-items: flex-end;
  flex-direction: column-reverse;
}

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <a class="navbar-brand" href="#">J & M Residential Cleaning Services</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>
  <div class="collapse navbar-collapse" id="navbarNav">
    <ul class="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="#">Book Online</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Contact Us</a>
      </li>
    </ul>
  </div>
</nav>

如果您想在展开 View 中对齐链接行，事情会变得有点复杂。 Bootstrap 4 已切换为 flexbox 布局，因此，您需要定位 .collapse.navbar-collapse，设置 align-items 为 flex-end 并更改 flex-direction 到列反转:

.collapse.navbar-collapse {
  align-items: flex-end;
  flex-direction: column-reverse;
}

这可以在下面看到(点击运行代码片段，然后点击完整页面):

.navbar- {
  text-align: right;
}

.collapse.navbar-collapse {
  align-items: flex-end;
  flex-direction: column-reverse;
}
