除非用户将鼠标悬停在小屏幕上，否则无法显示汉堡菜单

Question

除非用户将鼠标悬停在小屏幕上，否则无法显示Burger Menu。在Bulma.css中使用Angular。如果用户知道将鼠标悬停在哪里，则Burger菜单将按照指示工作。

期望用户在小屏幕（例如电话）的右上角看到汉堡菜单。除非用户知道将鼠标悬停在该位置上，否则什么都不会出现。一旦用户触摸，就会出现汉堡菜单。用户可以进行选择。出现“ X”，因此菜单将消失。

以下HTML代码

    <nav class="navbar is-link" role="navigation" aria-label="main navigation">
  <div class="navbar-brand">
    <a class="navbar-item" href="#">
      <img src="assets/img/bible2.png" />
    </a>

    <a
      (click)="toggleNavbar()"
      role="button"
      #navBurger
      class="navbar-burger burger is-active"
      aria-label="menu"
      aria-expanded="true"
      data-target="navbarBasicExample"
    >
      <span aria-hidden="true"></span>
      <span aria-hidden="true"></span>
      <span aria-hidden="true"></span>
    </a>
  </div>
