Question

我已经在vs代码编辑器中编写了代码，但是它不起作用：

Answer 1

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css">
<nav id="mainNavbar" class="navbar navbar-expand-lg navbar-dark bg-dark">
  <a class="navbar-brand" href="#">Candy</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navlinks" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>

  <div class="collapse navbar-collapse" id="navlinks">
    <ul class="navbar-nav mr-auto">
      <li class="nav-item active">
        <a class="nav-link" href="#">Home</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">About</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Tickets</a>
      </li>
    </ul>
  </div>
</nav>

您输入的错误

  

data-target =“ navlinks”

更改为

  

data-target =“＃navlinks”

谢谢！
