问题：如何在Bootstrap 3.2.0导航栏中获得最大化的搜索输入？
在Bootstrap 3.1.1中,我使用以下代码作为固定的底部导航栏来显示最大化的搜索输入.
<nav class="navbar navbar-default navbar-fixed-bottom" role="seasrch">
<div class="container">
<form class="navbar-form">
<div class="form-group">
<div class="input-group input-group-sm">
<div class="input-group-btn">
<a href="#" id="new_term" class="btn btn-default" role="button"><span class="glyphicon glyphicon-leaf"></span> New</a>
<a href="/terms.PHP" class="btn btn-default" role="button"><span class="glyphicon glyphicon-tree-deciduous"></span> All</a>
</div>
<input type="input" class="form-control" name="search_bar_text" />
<div class="input-group-btn">
<button class="btn btn-default"><span class="glyphicon glyphicon-search"></span></button>
</div>
</div>
</div>
</form>
</div>
</nav>
它看起来像这样：
升级到Bootstrap 3.2.0后,我的导航栏看起来像这样：
解决方法
我从3.1.1升级到3.2.0时遇到了同样的意外体验 – 我的(顶部)导航栏形式过去占据了屏幕的全宽,现在只是一个短元素.这是我在Boostrap之后加载的自定义CSS中有用的东西(这是我在保留原始干净缩小版本的同时覆盖Bootstrap的方式)：
/* Boostrap CSS 3.2.0 had these new lines in the navbar-form that
were different from 3.1.1 [it's all in @media (min-width: 768px)
so this behavior only shows up on higher resolutions] */
.navbar-form .input-group {
display: inline-table;
vertical-align: middle;
}
.navbar-form .input-group .input-group-addon,.navbar-form .input-group .input-group-btn,.navbar-form .input-group .form-control {
width: auto; /* HERE IS THE CULPRIT */
}
/** SOLUTION: in custom CSS **/
/* make sure navbar-form's input-group goes 100% i.e. full width of screen
to compliment the display: inline-table; that showed up in 3.2.0 */
.navbar-form .input-group {
width: 100%;
}
/* override width: auto; that showed up in 3.2.0
with at least 1px for the addon or btn (I had an addon) */
.navbar-form .input-group .input-group-addon,.navbar-form .input-group .input-group-btn {
width: 1px;
}
/* separate .form-control and give it width: 100%; */
.navbar-form .input-group .form-control {
width: 100%;
}
