视野头

<header>

      <a class="navbar-brand">Web</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 " id="navbarSupportedContent">
         <ul class="navbar-nav mr-auto">
