Rounded radius in twitter boostrap navbar - css

Question

There seems to be an odd border-radius of 4px on my navbar in my rails app using bootsrap 3 and I cant seem to get rid of it.
I've tried
.navbar { border-radius: none}
I can't even edit the bootstrap css because I cant seem to find it. Any eloquent work arounds?
Here the HTML
<nav class="navbar navbar-default" role="navigation">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<%= link_to "app", root_path , class: "navbar-brand" %>
</div>
<!-- Collect the nav links, forms, and other content for toggling -->
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
</li>
</ul>
<ul class="nav navbar-nav nav-pills navbar-right">
<li class="dropdown">
Dropdown <b class="caret"> </b>
<ul class="dropdown-menu">
<li>Action</li>
<li>Another action</li>
<li>Something else here</li>
<li class="divider"></li>
<li>Separated link</li>
</ul>
</li>
</ul>
</div><!-- /.navbar-collapse -->
</nav>

Answer 1

It's because none isn't a valid value for border-radius. From the specs, the values of border-radius are lengths or percentages. See the documentation.
You want the following:
.navbar { border-radius: 0; }
