How to make Bootstrap navbar brand image larger - html

Question

I am having a slight issue trying to increase the size of my navbar brand image i have inside my main navigation. It seem like it wont go any larger the 50px. I would like it around 100px high but just cant seem to work out how to do it. I currently have it in the center of the navigation with the burger menu along side it.
Would anyone know how to achieve what i am trying to do?
HTML:
<nav class="navbar navbar-default custom-nav">
<div class="container">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" 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" href="#"></a>

<ul class="nav navbar-nav">

</div>
<!-- /.navbar-collapse -->
</div>
<!-- /.container-fluid -->
</nav>
CSS:
.navbar-brand {
background: url(../img/logo.png);
background-position: center;
background-repeat: no-repeat;
background-size: contain;
width: 300px;
transform: translateX(-50%);
left: 50%;
position: absolute;
padding: 0;
}
.navbar-default .navbar-toggle .icon-bar {
background-color: #fff;
}
.navbar .navbar-nav {
display: inline-block;
float: none;
vertical-align: top;
}
.navbar .navbar-collapse {
text-align: center;
}
.custom-nav {
color: #fff;
background: #718373;
border-radius: 0;
margin-bottom: 0;
border: 0;
}
.custom-nav .navbar-nav>li>a {
color: #fff;
margin: 0 auto;
}
.custom-nav .navbar-nav>li>a:hover,
.custom-nav .navbar-nav>li>a:focus {
color: #fff;
}
.navbar-default .navbar-toggle:focus,
.navbar-default .navbar-toggle:hover {
background: none;
}
.custom-nav .navbar-nav>.open>a,
.custom-nav .navbar-nav>.open>a:focus,
.custom-nav .navbar-nav>.open>a:hover {
color: #fff;
background: none;
}
.custom-nav .navbar-nav li {
margin: 0 auto;
text-align: center;
width: 150px;
}
.dropdown-menu {
padding: 0;
margin: 0;
background: #718373;
border: none;
box-shadow: none;
min-width: 90px;
}
.dropdown-menu li:last-child a {
margin-bottom: 10px;
}
.dropdown-menu>li>a {
display: block;
clear: both;
font-weight: normal;
color: #fff;
width: 95%;
margin: 0 auto;
text-align: center;
padding: 20px 0;
}
.dropdown-menu>li>a:focus,
.dropdown-menu>li>a:hover {
color: #fff;
text-decoration: none;
background: none;
outline: 2px solid white;
outline-offset: -2px;
}
This is how it looks at the moment
EDIT after adding
.navbar-header .navbar-brand {
height: 100px;
}

Answer 1

Your styles are overwritten by Bootstraps navbar styles. Use higher specificity to make your styles apply to the navbar-brand, e.g. with
.navbar-header .navbar-brand {
height: 100px;
}
This way you can overwrite the height.
.navbar-header .navbar-brand {
background: url(../img/logo.png);
background: url(//placehold.it/300x100);
background-position: center;
background-repeat: no-repeat;
background-size: contain;
height: 100px;
width: 300px;
transform: translateX(-50%);
left: 50%;
position: absolute;
padding: 0;
: #fff;
}
.navbar .navbar-nav {
display: inline-block;
float: none;
vertical-align: top;
}
.navbar .navbar-collapse {
text-align: center;
}
.custom-nav {
color: #fff;
background: #718373;
border-radius: 0;
margin-bottom: 0;
border: 0;
}
.custom-nav .navbar-nav>li>a {
color: #fff;
margin: 0 auto;
}
.custom-nav .navbar-nav>li>a:hover,
.custom-nav .navbar-nav>li>a:focus {
color: #fff;
}
.navbar-default .navbar-toggle:focus,
.navbar-default .navbar-toggle:hover {
background: none;
}
.custom-nav .navbar-nav>.open>a,
.custom-nav .navbar-nav>.open>a:focus,
.custom-nav .navbar-nav>.open>a:hover {
color: #fff;
background: none;
}
.custom-nav .navbar-nav li {
margin: 0 auto;
text-align: center;
width: 150px;
}
.dropdown-menu {
padding: 0;
margin: 0;
background: #718373;
border: none;
box-shadow: none;
min-width: 90px;
}
.dropdown-menu li:last-child a {
margin-bottom: 10px;
}
.dropdown-menu>li>a {
display: block;
clear: both;
font-weight: normal;
color: #fff;
width: 95%;
margin: 0 auto;
text-align: center;
padding: 20px 0;
}
.dropdown-menu>li>a:focus,
.dropdown-menu>li>a:hover {
color: #fff;
text-decoration: none;
background: none;
outline: 2px solid white;
outline-offset: -2px;
