html - Bootstrap : Extra Space in Collapsed Navbar between the brand name and the 3 Horizontal bars drop-down button

Question

我正在为我的页面创建一个固定顶部导航栏，当导航栏折叠时(例如，对于小视口(viewport))，“品牌”名称和展开菜单图标之间有额外的空间。

这是正在发生的事情的图片: Extra Space in Collapsed Navbar

这是我的导航栏代码:

<nav class="navbar navbar-inverse navbar-fixed-top" role="navigation">
<div class ="container">
        <div class="navbar-header"><a class="navbar-brand" href="#">Brand</a></div>
        <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#navTop">
            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
        </button>
    <div class="navbar-collapse collapse" id="navTop" aria-expanded="false" style="height: 1px;">
        <ul class="nav navbar-nav">
            <li>
                <a href="#">About</a>
            </li>
        </ul>
        <ul class="nav navbar-nav navbar-right">
            <li>
                <form class="navbar-form" role="search">
                    <div class="input-group">
                        <input type="text" class="form-control" placeholder="Search" name="srch-term" id="srch-term">
                        <div class="input-group-btn">
                            <button class="btn btn-default" type="submit"
                            style="padding-bottom: 7px;"><i class="glyphicon glyphicon-search"></i></button>
                        </div>
                    </div>
                </form>
            </li>
        </ul>
    </div>
</div>

你能帮我弄清楚如何删除多余的空间吗？谢谢!

您的 navbar-header 应该包含按钮，它目前在按钮开始之前结束。此外，(取决于您的用例)表单不需要位于 ul 内，如果确实如此，则会导致显示问题。参见 Docs
