Question

我不是经验丰富的Bootstrap用户，而且我遇到以下问题：

<header class="header">
  <nav class="primary-nav navbar navbar-default navbar-fixed-top" role="navigation">
    <div class="container-fluid">
      <div class="navbar-header">
        <button class="navbar-toggle" data-target="#primary-nav" data-toggle="collapse" type="button">
          <span class="sr-only">Toggle navigation</span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
        </button>
        <a class="navbar-brand" href="index.html">Hello</a>
      </div>
      <div class="collapse navbar-collapse" id="primary-nav">
        <ul class="nav navbar-nav navbar-right">
          <li class="active"><a href="index.html">Welcome</a></li>
          <li><a href="#">Foo</a></li>
          <li><a href="#">Bar</a></li>
        </ul>
        <form class="search navbar-form navbar-right" role="search">
          <div class="form-group">
            <label class="has-clear">
              <input autocapitalize="off" autocomplete="off" autocorrect="off" class="form-control" id="search-input" placeholder="Search..." type="text">
              <span aria-hidden="true" class="form-control-clear glyphicon " id="clear-search"></span>
            </label>
          </div>
        </form>
      </div>
    </div>
  </nav>
</header>

通过这个非常简单的导航栏设置，有两件事我难以纠正：

我不明白为什么我需要自定义CSS来摆脱搜索框margin-bottom，imho 股票引导CSS应该处理这个但也许我＆＃39 ;我犯了一个错误
我无法找到一种方法可靠地使搜索输入填充导航栏的宽度而不指定px中的绝对宽度

虽然我可以管理1.但是我无法为导航栏的搜索输入获得正确的行为，该输入应该占据全宽并且当＆＃34; hamburger＆＃34;菜单出现。

提前感谢您的帮助。
