Question

在台式机版本的导航栏中，我无法使输入字段的流体宽度达到100％。

<nav class="navbar navbar-inverse navbar-fixed-top">
 <div class="container-fluid">
  <div class="navbar-header">
      <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar">
        <span class="sr-only">Menu</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <a class="navbar-brand" href="#"><img src="https://via.placeholder.com/100x30.png?text=Logo" width="100" height="25" /></a>
  </div>
  <div id="navbar" class="navbar-collapse collapse">
    <div class="nav navbar-nav">
      <div class="navbar-form">
        <div class="input-group">
          <input type="url" class="form-control" placeholder="http://www.website.com" name="url" value="" />
          <span class="input-group-btn">
            <button class="btn btn-success" type="button" id="seo-submit">Submit</button>
          </span>
        </div>
      </div>
    </div>
    <ul class="nav navbar-nav navbar-right">
      <li>
        <a href="#">Item 1</a>
      </li>
      <li>
        <a href="#">Item 2</a>
      </li>
      <li>
        <a href="#">Item 3</a>
      </li>
    </ul>
  </div>
 </div>
</nav>

有什么想法可以使输入栏和按钮填满导航栏空间，同时保持内联？

您将需要对CSS和HTML进行一些更改。

在HTML上，我将类navbar-left添加到菜单div中。现在在CSS上，我们可以使用一些flexbox属性来使每件事变得更加流畅。

我使用媒体查询进行了编码，因此您需要添加它们，以便您的移动布局保持完整。

在整页中测试此代码段

div#navbar {
      display: flex!important;
}

.navbar-left{
    flex-grow: 1;
}
      
.navbar-nav {
      float: none!important;
    }

.navbar-form .input-group,
.navbar-inverse .navbar-form,
.input-group-btn:last-child>.btn{
     width: 100%; 
     
}

          </li>
          <li>
            <a href="#">Item 3</a>
          </li>
        </ul>
      </div>
    </div>
  </nav>

希望这会有所帮助：）
