在较小的设备上查看时如何在顶部中心显示徽标

Question

我在 header 菜单栏中有一个徽标。徽标出现在 header 的左上角。当我在较小的设备上查看时，徽标隐藏在汉堡菜单中。有没有办法在较小的设备上查看时我们可以在顶部中心显示徽标，如果在较大的设备上查看时与原样相同，这意味着左上角

我正在使用 bootstrap 3.3.7

 <nav class="navbar navbar-default navbar-fixed-top" role="navigation">
        <div class="navbar-inner">
            <div class="navbar-header">
                <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
                    <span class="sr-only">Toggle navigation</span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                </button>
            </div>

            <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
                <div class="navbar-logo">
                    <img src="Images/Logo.jpg" ui-sref="homeIndex" style="cursor:pointer;" alt="Virginia System of Care" height="60" width="140" />
                </div>
                <ul class="nav navbar-nav">
                    <li><a ui-sref="homeIndex">Home</a></li>
        </ul>
            </div><!-- /.navbar-collapse -->
        </div>
    </nav>

Answer 1

我更改了图片的位置，因此它无法在小分辨率下隐藏，对于小分辨率的中心徽标，我添加了一些仅适用于小分辨率的 CSS

@media only screen and (max-width: 768px) {
  .navbar-brand {
    position: absolute;
    left: 50%;
    transform: translateX(-50%);
  }
}

@media only screen and (max-width: 768px) {
  .navbar-brand {
    position: absolute;
    left: 50%;
    transform: translateX(-50%);
  }
}
