Full-width secondary navbar inside parent navbar with Bootstrap - css

Question

I'm trying to create a pretty simple double-navbar effect with Bootstrap. The only problem I have right now is that the second/bottom navbar isn't stretching across the whole browser width. Here's my code...
<nav class="navbar navbar-fixed-top navbar-inverse">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar" style = "line-height: 30px;">
<span class="sr-only">Toggle navigation</span>
<span class="glyphicon glyphicon-menu-hamburger" style="color:#fff;"></span>
</button>
<a class="navbar-brand" href="#" style = "line-height: 30px;">brand</a>
</div>
<div id="navbar" class="collapse navbar-collapse">
<ul class="nav navbar-nav">
<!-- <li>Button</li> -->
</ul>
</div><!-- /.nav-collapse -->
<!-- this is the second navbar element that never takes up the full width available-->
<div class="nav navbar-default" style="background-color: #66CCFF;">
<ul class="nav navbar-nav">
<li></li>
<li class="divider-vertical"></li>
<li></li>
<li class="divider-vertical"></li>
<li></li>
</ul>
</div>
</div><!-- /.container -->
</nav><!-- /.navbar -->
I've played with various different navbar types and css styles (e.g. width:100%), but I can't seem to figure out how to make the second navbar (i.e. the one containing the 3 glyphicons) the same width as its parent.
Really appreciate any ideas on what I might be doing wrong!

Answer 1

You need to use container-fluid instead of container since latter has a fixed width.
.container-fluid still contains CSS rules for padding. You may try to overwrite it using custom class.
.container-fluid.no-padding {
padding: 0;
}
.no-padding .navbar-header {
padding-left: 10px; /* Align the Brand text */
}
#media (max-width: 768px) {
.no-padding .navbar-nav {
padding-left: 10px; /* Align the icons on small screens */
}
}

<nav class="navbar navbar-fixed-top navbar-inverse">
<div class="container-fluid no-padding">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar" style="line-height: 30px;">
<span class="sr-only">Toggle navigation</span>
<span class="glyphicon glyphicon-menu-hamburger" style="color:#fff;"></span>
</button>
<a class="navbar-brand" href="#" style="line-height: 30px;">brand</a>
</div>
<div id="navbar" class="collapse navbar-collapse">
<ul class="nav navbar-nav">
<!-- <li>Button</li> -->
</ul>
</div>
<!-- /.nav-collapse -->
<!-- this is the second navbar element that never takes up the full width available-->
<div class="nav navbar-default" style="background-color: #66CCFF;">
<ul class="nav navbar-nav">
<li>
</li>
<li class="divider-vertical"></li>
<li>
</li>
<li class="divider-vertical"></li>
<li>
</li>
</ul>
</div>
</div>
<!-- /.container -->
</nav>
<!-- /.navbar -->

.navbar > .container {
padding-left: 0;
padding-right: 0;
}
just removing the padding from container changes all the instances of container on your page.
you then want to add padding back to your navbar-header
.navbar > .container {
padding-left: 0;
padding-right: 0;
}
.navbar .navbar-header {
padding: 5px 10px;
}
