如何将 Navbar-Brand 居中在链接项的中间

Question

我的导航菜单有问题。

我想要的是我的品牌位于导航链接的中间。

示例 Home | product | Company Logo(this is my brand) | about us | contact us。

当我在小型设备中打开时，我希望公司徽标停留在导航栏的当前位置或中间，当我单击切换图标时，其他链接项 (home|product|about us|contact us) 会显示。

下面是我的源代码：

        <div class="collapse navbar-collapse" id="navigation">
            <ul class="navbar-nav">
                  <li class="nav-item active">
                    <a class="nav-link" href="#">About Us <span class="sr-only">(current)</span></a>
                  </li>
                      <li class="nav-item">
                        <a class="nav-link" href="#">Products</a>
                      </li>
                          <li class="nav-item dropdown">
                          <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Dropdown
                          </a>
                                <div class="dropdown-menu" aria-labelledby="navbarDropdown">
                                      <a class="dropdown-item" href="#">Action</a>
                                      <a class="dropdown-item" href="#">Another action</a>
                                      <div class="dropdown-divider"></div>
                                      <a class="dropdown-item" href="#">Something else here</a>
                                </div>
                          </li> 


        <a class="narbar-brand">Company Name</a><!-- I want this company name stay at top when I open my website via small device -->

                  <li class="nav-item">
                    <a class="nav-link" href="#">Suppport and Downloads</a>
                  </li>
                      <li class="nav-item">
                        <a class="nav-link" href="#">Partners</a>
                      </li>
                      <li class="nav-item">
                        <a class="nav-link" href="#">Contact Us</a>
                      </li>
            </ul>
            <!--<form class="form-inline my-2 my-lg-0">
              <input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
              <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
            </form>-->
        </div>
    </nav>

以下是大/小屏幕设备中的示例导航。我希望公司名称出现在小型设备上

您可以为此使用媒体查询并创建两个导航品牌元素

a.navbar-brand.center {
  display: none;
}


@media (max-width: 990px) {
  
  a.navbar-brand {
        display:none;
  }
  
  a.navbar-brand.center {
    position: absolute;
    display: block;
    transform: translate(-50%);
    left: 50%;
    top: 10px;
  }
    
  li.nav-item {
    text-align: center;
  }
}

Answer 2

使用下面的自定义css可以实现

.navbar-header .navbar-brand{
  display:none;
}
.nav-item .navbar-brand{
    font-size: 18px;
    font-weight:bold;
}
@media only screen and (max-width: 767px) {
  .navbar-header .navbar-brand{
    display:block;
  }
  .nav-item .navbar-brand{
    display:none;
  }
}
