Question

我在标题菜单栏中有一个徽标。徽标出现在标题的左上角。在较小的设备上查看徽标时，汉堡菜单中隐藏了徽标。在较小的设备上查看时，是否有办法在顶部居中显示徽标，如果在相同的较大设备上查看，则意味着左上角

我正在使用引导程序3.3.7

handleChange(e) {
    const resultList = this.state.list.slice();
    resultList[e.target.id] = e.target.value;
    this.setState({
      list: resultList,
      result: this.doSomething(resultList) // this.doSomething(this.state.list)
    });
  }

我更改了图像的位置，因此不能以小分辨率隐藏它，而以小分辨率隐藏中心徽标，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%);
  }
}
