html - 我想将导航项注册向右移动，我尝试了 ml-auto 和 justify-content-end 但它没有移动

问题描述

尝试使用 Bootstrap 4 通过 ml-auto 和 justify-content-end 将导航项“注册”移动到右侧，但它没有移动。

<nav class="navbar navbar-expand-lg navbar-dark bg-danger">
    <div class="container">
        <a class="navbar-brand" href="#">Navbar</a>
        <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>
        </button>
        <div class="collapse navbar-collapse justify-content-end" id="navbarSupportedContent">
            <ul class="navbar-nav mr-auto">
                <li class="nav-item">
                    <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Link</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Contact</a>
                </li>
            </ul>
            <ul class="navbar-nav mr-auto">
                <li class="nav-item">
                    <a class="nav-link" href="#">Sign Up</a>
                </li>
            </ul>
        </div>
    </div>
</nav>

解决方案

只需从 ul 标记中删除“mr-auto”类，然后在 css 下方添加。

.navbar-nav.rightSide {
  display: flex;
  justify-content: flex-end;
  flex-grow: 1;
}

<nav class="navbar navbar-expand-lg navbar-dark bg-danger">
  <div class="container">
    <a class="navbar-brand" href="#">Navbar</a>
    <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>
			</button>
    <div class="collapse navbar-collapse justify-content-end" id="navbarSupportedContent">
      <ul class="navbar-nav">
        <li class="nav-item">
          <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Link</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Contact</a>
        </li>
      </ul>
      <ul class="navbar-nav rightSide">
        <li class="nav-item">
          <a class="nav-link" href="#">Sign Up</a>
        </li>
      </ul>
    </div>
  </div>
</nav>
