bootstrap3: Make navbar link underlined - html

Question

I'm working on a bootstrap 3 website and I want to make the links in the navbar underlinded with the help of the border, something like this:
But at the moment it looks like this:
I tried the "padding-bottom" atribute, but that does nothing.
My html:
<nav class="navbar navbar-default navbar-fixed-top">
<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">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand navbar-left" href="/index.html"><img class="nav-logo" src="/images/xcellent-logo/logo.png"></a>
</div>
<div id="navbar" class="navbar-collapse collapse">
<ul class="nav navbar-nav nav-underline">
<li class="dropdown">
Services<span class="caret"></span>
<ul class="dropdown-menu">
<li>stuff</li>
<li>stuff</li>
<li>stuff</li>
<li>stuff</li>
<li>stuff</li>
</ul>
</li>
<li>stuff</span></li>
<li>stuff</span></li>
<li>stuff</span></li>
</ul>
</div><!--/.nav-collapse -->
</div>
</nav>
The CSS I tried:
.nav-underline a {
border-bottom: transparent solid 2px;
padding-bottom: 40px;
}
.nav-underline a:hover {
border-bottom: $white solid 2px;
}
Is there a way to achieve this? Thanks for your help!

Just shift the padding of anchor to li. Here is the custom css for the
same.
.navbar-nav.nav-underline>li>a {
padding: 0px;
}
.navbar-nav.nav-underline>li {
padding: 15px;
}
Below is the working example:
.nav-underline a {
border-bottom: transparent solid 2px;
padding-bottom: 40px;
}
.nav-underline a:hover {
border-bottom: red solid 2px;
}
.navbar-nav.nav-underline>li>a {
padding: 0px;
}
.navbar-nav.nav-underline>li {
padding: 15px;
}
