Question

因此，默认情况下，Bootstrap会在左下角显示徽标，但在调整大小时仍然在左侧。我想把它放在中间以使其显示更好。

我拥有的图像： What i have

我想要展示的图片： What i want

我有这个代码在Wordpress中显示Bootstrap菜单：

<header>
  <div class="menu">
    <nav class="navbar navbar-default navbar-static-top">
      <div class="container" id="menu2">
        <div class="navbar-header">
          <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#menu1">
            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            </button>
            <a class="navbar-brand" href="<?php echo esc_url( home_url( '/' ) ); ?>">
              <img alt="Logo" src="<?php bloginfo('template_url');?>/img/logo.png">
            </a>
          </div>
          <div class="navbar-collapse collapse col-md-9" id="menu1">
            <?php wp_nav_menu(array(
                'theme_location' => 'primary',
                'container' => false,
                'menu_class' => 'nav navbar-nav navbar-right'));
              ?>

          </div>

        </nav>
      </div>
</header>

我尝试了text-align：center，但它仅适用于链接，不适用于徽标

Answer 1

您可以使用徽标在中心重写标题的不同布局，并使用引导辅助类使可见的标题可见。供你参考。 http://getbootstrap.com/css/#responsive-utilities

另一种方法是使用偏移 http://getbootstrap.com/css/#grid-offsetting

Answer 2

好的，我通过添加以下内容解决了这个问题：

    @media (min-width:768px) {
  .navbar .navbar-nav {
      display: inline-block;
      float: none;
  }

  .navbar-brand{
    display: inline-block;
    float: none !important;
  }

  .navbar .navbar-collapse {
      text-align: center;
      margin: 0 auto;
  }

  .navbar-nav > li {
      display: inline-block;
      float:none;
  }
}

@media(max-width:1200px) {
.navbar-header {
        text-align: center;
        margin: 10px;
        float: none !important;
    }
  }

现在，当没有空间且链接断开时，品牌标识就会居中。

我还创建了没有Wordpress的干净Bootstrap导航栏示例，以便其他想要查看其工作原理的用户 （运行并在全屏显示并调整窗口大小以查看效果）：< / p>
