Bootstrap 3.1.1 Nav Bar Maximized Input No Longer Maximized in 3.2.0

css, html, twitter-bootstrap

Solution

I had the same unexpected experience as I upgraded from 3.1.1 to 3.2.0 - my (top) navbar-form which used to take full width of the screen was now just a short element. This is what worked for me in my custom CSS that loads up after Boostrap (that's how I override Bootstrap while preserving their original clean minified version):

/* 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%;
}

Problem

Question: How can I get a maximized search input in a Bootstrap 3.2.0 nav bar? In Bootstrap 3.1.1 I used the following code for a fixed bottom nav bar to display a maximized search input. ``` <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>&nbsp;&nbsp;New</a> <a href="/terms.php" class="btn btn-default" role="button"><span class="glyphicon glyphicon-tree-deciduous"></span>&nbsp;&nbsp;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> ``` And it looked like this: My nav bar looks like this, after upgrading to Bootstrap 3.2.0:
