列表项导航栏的对齐方式bootstrap 3.3.6

Question

请参阅下面的代码或此 bootply

我遇到了一些严重的问题。

我的问题：

我无法很好地对齐导航栏中的所有项目。有什么想法吗？
不想在手机版显示搜索栏，怎么省略？

试图在 css 代码中插入用于搜索的 bootstrap 字形而不是图像，但是如何触发 css 中的字形，我可以吗让它变黑还是变白？

<nav class="navbar navbar-inverse navbar-fixed-top my-navbar">
  <div class="container">
    <!-- Brand and toggle get grouped for better mobile display -->
    <div class="navbar-header">
      <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>

Answer 1

搜索按钮，试试font-awesome，会更好看（有white/black版本（http://fontawesome.io/icon/search/））

参考这个link：How to center navbar elements vertically (Twitter Bootstrap)? 对于垂直居中

使用此功能（将 class 设置为 hidden-phone hidden-tablet）删除移动设备上的搜索

<li class="hidden-phone hidden-tablet">
                    <form class="navbar-form navbar-left searchsite" role="search">
                        <div class="form-group">
                            <input type="text" class="form-control" placeholder="Search">
                        </div>
                            <button type="submit" class="btn btn-default">Submit</button>
                    </form>
                </li>

希望对您有所帮助！（如果有效，请尝试接受答案）:)

Answer 2

错位是由于 height 您在 .navbar-right
要在移动设备中隐藏搜索，您可以使用 hidden-xs
要使用 search 图标，您可以使用 bootstrap 已有的字形。你可以查看它们 here

.glyphicon-search {
  color: white
}

Answer 3

添加这个 CSS:

@media (min-width: 768px) {
    .navbar .navbar-brand {
        padding: 20px 15px;
    }

    .navbar .nav:not(.navbar-right) > li > a {
        padding: 20px 15px;
    }

    .navbar-form {
        margin-top: 14px;
    }
}

navbar-right 中的图像导致导航栏高 60 像素，而不是默认的 50 像素，20 像素的填充将使元素居中。

要在移动设备上隐藏搜索栏，您可以添加 class hidden-xs:

<form class="navbar-form navbar-left searchsite hidden-xs" role="search">
</form>
