Bootstrap comes with a complete solution for navigation bars. If you want to find out more about how to create one and align the items inside it, check out our Bootstrap 4 navbar tutorial where we go into details.
The design is improved inside the Lazy Kit. Here is how a basic example looks like.
<nav class="navbar navbar-expand-lg navbar-dark bg-primary">
<div class="container">
<a class="navbar-brand d-flex align-items-center" href="#lazy">Lazy Kit</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavDropdown-1" aria-controls="navbarNavDropdown-1"
aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse text-center" id="navbarNavDropdown-1">
<ul class="navbar-nav ml-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home
<span class="sr-only">(current)</span>
</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricing</a>
</li>
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#a" id="navbarDropdownMenuLink" data-toggle="dropdown"
aria-haspopup="true" aria-expanded="false">
Services
</a>
<div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
<a class="dropdown-item" href="#">Design</a>
<a class="dropdown-item" href="#">Development</a>
<a class="dropdown-item" href="#">Marketing</a>
</div>
</li>
</ul>
</div>
</div>
</nav>
You can modify the color of the navbar using the background color utilities. Here is an example with the info background.
<nav class="navbar navbar-expand-lg navbar-dark bg-info">
<div class="container">
<a class="navbar-brand d-flex align-items-center" href="#lazy">Lazy Kit</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavDropdown-3" aria-controls="navbarNavDropdown-3"
aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse mr-auto text-center" id="navbarNavDropdown-3">
<ul class="navbar-nav ml-auto">
<li class="nav-item">
<a class="nav-link" href="#">
<i class="fab fa-twitter"></i> Twitter
</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">
<i class="fab fa-facebook-f"></i> Facebook
</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">
<i class="fab fa-github"></i> Github
</a>
</li>
</ul>
</div>
