Bootstrap 3 navbar height after resize - html

Question

I'm trying to put the height of the navigation bar at 40px after resize the page, but when I put it and I resize the web page, the height of the navbar is higher than 40px, I tried it with
#media (min-width:768px){
#barranavegacion{
background-color:#333;
border: none;
height: 40px;
}
}
The website is: http://vuelos.gangatravel.es/ to see my problem easily after resize the page.
Navbar code:
<nav class="navbar navbar-inverse navbar-fixed-top" id="barranavegacion" >
<div class="container-fluid">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#menu" aria-expanded="false">
<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">
<img style="max-width:100px; margin-top: -7px;" src="http://pixelup.wc.lt/up/img/cc3c887b0f.png" />
</a>
</div>
<div class="collapse navbar-collapse" id="menu">
<ul class="nav navbar-nav">
<li class="active"><a style="font-size: 14pt;" href="#">Vuelos <span class="sr-only">(current)</span></a></li>
<li><a style="font-size: 14pt;" href="http://hoteles.gangatravel.es/" target="_blank">Hoteles</a></li>
<li><a style="font-size: 14pt;" href="#">Coches</a></li>
<li><a style="font-size: 14pt;" href="http://rutas.gangatravel.es/es/s/" target="_blank">Rutas</a></li>
</ul>
<ul class="nav navbar-nav navbar-right">
<li><img style="max-width: 30px; max-height: 30px; margin-top: -12px;" src="http://pixelup.wc.lt/up/img/29ed8fbcb8.png"/></li>
<li><img style="max-width: 30px; max-height: 30px; margin-top: -12px;" src="http://pixelup.wc.lt/up/img/ffb14b6235.png"/></li>
<li><img style="max-width: 30px; max-height: 30px; margin-top: -12px;" src="http://pixelup.wc.lt/up/img/c38838d8fa.png"/></li>
<li><img style="max-width: 30px; max-height: 30px; margin-top: -12px;" src="http://pixelup.wc.lt/up/img/73a02977d4.png"/></li>
</ul>

</nav>

Answer 1

The problem comes with the bootstrap's .navbar css: min-height: 50px;
#media (min-width:768px){
#barranavegacion{
background-color:#333;
height: 40px;
min-height: 40px;
}
}
IMPORTANT NOTE: This will do the trick, but there are more inner elements, such as container-fluid, which uses min-height: 50px;.

Answer 2

Try this :
#media (min-width:768px){
#barranavegacion{
background-color:#333;
border: none;
height: 40px !important;
max-height: 40px !important;
}
}
