  <nav class="navbar navbar-inverse">
    <div class="container-fluid">
      <div class="navbar-header">
        <a class="navbar-brand" href="#">WebSiteName</a>
      </div>
      <ul class="nav navbar-nav">

      <ul class="nav navbar-nav navbar-right">
        <li><a href="#"><span class="glyphicon glyphicon-user"></span> Sign Up</a></li>
        <li><a href="#"><span class="glyphicon glyphicon-log-in"></span> Login</a></li>

BS 4 中没有字形，你必须使用 Font Awesome。由于 BS 4 包含 flexbox，您可以使用ml-auto(align-right) 和mr-auto(align-left)对齐元素。
