引导搜索全宽(bootstrap search full width)

有这个例子。 https://jsfiddle.net/sea2sw25/1/

但始终保持顶部的搜索字段，并且还在767px以下。这是可能的？搜索字段的全部宽度总是？

谢谢。

<nav class="navbar navbar-inverse navbar-fixed-top" role="navigation"> <div class="container">  <div class="navbar-header"> <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1"> <span class="sr-only">MAIN</span> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button> <a class="navbar-brand hidden-xs" href="">BootStrap</a> <a class="navbar-brand visible-xs" href="">B</a> </div>  <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"> <ul class="nav navbar-nav navbar-right"> <li> <a href="about.html">Abount</a> </li> <li> <a href="services.html">Services</a> </li> <li> <a href="contact.html">Contact</a> </li> </ul> <form class="navbar-form"> <div class="form-group" style="display:inline;"> <div class="input-group" style="display:table;"> <input class="form-control" name="search" placeholder="Search" autocomplete="off" autofocus="autofocus" type="text"> <span class="input-group-addon" style="width:1%;"><span class="glyphicon glyphicon-search"></span></span> </div> </div> </form> </div>  </div>  </nav>

There is this example. https://jsfiddle.net/sea2sw25/1/

But always keep the top search field, and also 767px below. It's possible? Search field full width always?

Thank you.

做到这一点的一种方法是将表单放置在navbar-header内，以便它始终保持公开，然后使用媒体查询来控制表单的宽度，使其不包含链接等。

One way to do this is to place the form inside the navbar-header so it will remain exposed at all times, then use media queries to control the width of the form so it doesn't cover your links etc.
