I have a big doubt on the bootstrap, I created a Navbar using the default bootstrap classes .... the problem is that I can not centralize a logo in the center of the navbar, it works only from left to right. of a solution that is standard bootstrap, so the code is.
<nav class="navbar navbar-default">
<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="#">
<img alt="Brand" src="img/logo-3.svg" width="50px">
</a>
</div>
