Question

我希望标题栏包含三个元素，如下面的

但在移动视图中，我希望菜单（切换图标）向左移动，徽标应该在中间。我试着推拉。但这对我不起作用。无论如何我能做到这一点吗？

这是我的代码。仅供参考，我还没有添加任何单独的媒体查询。只需使用引导类。

<div class="row d-flex flex-nowrap" style="background-color: #2B3536;">
    <div class="col-lg-1 col-md-1 col-sm-2 col-2 align-self-center"><img src="https://dummyimage.com/127x50/2b3536/fff"></div>
    <div class="col-lg-8 col-md-9 col-sm-8 col-8 order-sm-first">
        <nav class="navbar navbar-fixed-top navbar-toggleable-sm navbar-expand-sm">
            <div class="container d-flex flex-row flex-md-nowrap flex-wrap">
              <a href="#" class="hidden-md-up mr-3" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false">

Answer 1

您应该将媒体查询添加到样式css文件

.navbar-brand{
   padding-top:8px;
 }
.navbar-brand img{
   height:35px;
    width:35px
}

@media (max-width:767px) {
  .navbar-brand{
    position: absolute;
    left: 40%;
  }
}

.navbar-toggle {
  float: left;
}

您可以查看活动演示menu design
