Bootstrap3 - Change navbar size
<p>I'm new to Bootstrap and I want to change the height of my navbar. I've seen some topics about that but nothing solved my problem. I took the navbar code from a theme so i don't understand all of the code yet. Tried to change the height of navbar class but there are many of them so i'm quite confused.</p>

<p>navbar class from index.html : </p>

<pre><code>&lt;nav class="navbar navbar-inverse navbar-fixed-top" role="navigation" &gt;
    &lt;div class="container" &gt;
        &lt;!-- Brand and toggle get grouped for better mobile display --&gt;
        &lt;div class="navbar-header"&gt;
            &lt;button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1"&gt;
                &lt;span class="sr-only"&gt;Toggle navigation&lt;/span&gt;
                &lt;span class="icon-bar"&gt;&lt;/span&gt;
                &lt;span class="icon-bar"&gt;&lt;/span&gt;
                &lt;span class="icon-bar"&gt;&lt;/span&gt;
            &lt;/button&gt;
            &lt;a class="navbar-left" href="#"&gt;&lt;img src="images/_ressources/logo.svg" height="50px"&gt;&lt;/a&gt;
        &lt;/div&gt;
        &lt;!-- Collect the nav links, forms, and other content for toggling --&gt;
        &lt;div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"&gt;
            &lt;ul class="nav navbar-nav"&gt;
                &lt;li&gt;
                    &lt;a href="#" style="font-family: 'Roboto', sans-serif;"&gt;ACCUEIL&lt;/a&gt;
                &lt;/li&gt;
                &lt;li&gt;
                    &lt;a href="#" style="font-family: 'Roboto', sans-serif;"&gt;BOUTIQUE&lt;/a&gt;
                &lt;/li&gt;
                &lt;li&gt;
                    &lt;a href="#" style="font-family: 'Roboto', sans-serif;"&gt;CONTACT&lt;/a&gt;
                &lt;/li&gt;
            &lt;/ul&gt;

          &lt;ul class="nav navbar-nav navbar-right"&gt;
            &lt;li&gt;
              &lt;a href="#" style="font-family: 'Roboto', sans-serif;"&gt;MON COMPTE&lt;/a&gt;
            &lt;/li&gt;
            &lt;li&gt;
              &lt;div class="input-group-btn"&gt;
                &lt;button type="button" class="btn btn-default btn-lg" style="background-color:orange"&gt;
                  &lt;span class="glyphicon glyphicon-lock" &gt;&lt;/span&gt;
                &lt;/button&gt;
            &lt;/div&gt;
            &lt;/li&gt;

          &lt;/ul&gt;

      &lt;form class="navbar-form navbar-right" role="search"&gt;
        &lt;div class="input-group"&gt;
            &lt;input type="text" class="form-control" placeholder="Recherche un produit"&gt;
            &lt;div class="input-group-btn"&gt;
                &lt;button class="btn btn-default" type="submit"&gt;&lt;i class="glyphicon glyphicon-search"&gt;&lt;/i&gt;&lt;/button&gt;
            &lt;/div&gt;
        &lt;/div&gt;
      &lt;/form&gt;
          &lt;!-- /.navbar-collapse --&gt;
      &lt;/div&gt;
    &lt;/div&gt;
    &lt;!-- /.container --&gt;
&lt;/nav&gt;
