像这样在 ul 标签前使用弹性间隔物

<span class="flex-spacer"></span>

在css中添加类

.flex-spacer {
  flex: 1 1 auto;
}

您的代码将是

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">HOMEPAGE</a>
    <div class="collapse navbar-collapse" id="navbarSupportedContent">
      <span class="flex-spacer"></span>
      <ul class="navbar-nav me-auto mb-2 mb-lg-0">
        <span class="navbar-text">
          <a routerLink="/homepage/registration">Registration</a>
        </span>
        <span class="navbar-text">
          <a routerLink="/homepage/login">Login</a>
        </span>
      </ul>
    </div>
  </div>
</nav>
<router-outlet></router-outlet>

这是它的样子

希望这有帮助。

将 CSS 应用到您的组件

#navbarSupportedContent{
  position: absolute;
  float: right;
  right: 20px;
}

.navbar-nav{
  gap: 10px;
}
