整个 Bootstrap 导航栏都是 png？

海瑞曼

我一直在浏览引导程序文档，所有示例都展示了如何在基本导航栏上添加一个简单的徽标。

我设计了我想用作导航栏的 .png 文件。这是可能的吗？

然后我想在 png 顶部添加导航链接等，因为我会将它们添加到常规导航栏。

<style type="text/css">
.bgimg {
    background-image: url('bannerReal.png');
}
</style>

</head>

<body>

  <!-- Navigation -->
  <nav class="navbar navbar-expand-lg navbar-dark bg-dark static-top bgimg>
    <div class="container">
      <a class="navbar-brand" href="#">Start Bootstrap</a>
      <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
      </button>
      <div class="collapse navbar-collapse" id="navbarResponsive">
        <ul class="navbar-nav ml-auto">
          <li class="nav-item active">
            <a class="nav-link" href="#">Home
              <span class="sr-only">(current)</span>
            </a>
          </li>
          <li class="nav-item">
            <a class="nav-link" href="#">About</a>
          </li>
          <li class="nav-item">
            <a class="nav-link" href="#">Services</a>
          </li>
          <li class="nav-item">
            <a class="nav-link" href="#">Contact</a>
          </li>
        </ul>
      </div>
    </div>
  </nav>

您粘贴的代码应该可以工作……前提是您在加载 bootstrap.css 文件后添加了样式块……您可以检查下面的代码段并进行验证。

.bgimg {
  background: url(https://s3.amazonaws.com/seekadventure.net.storage/bannerReal.png);
  background-position: bottom;
  background-size: cover;
}

    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">

            </a>

        </li>
      </ul>
    </div>
  </div>
</nav>
