Bootstrap - Fluid navbar items - css

Question

I'm a newbie bootstrap user, currently I want to create a fluid navigation bar, but when I shrink the browser the navigation bar becomes weird.
Before shrinking:
After shrinking further:
As you can see, the second image is pretty bad.. One possible way I thought is to separate the words into 2 lines (e.g. line 1 - goto, line 2 - Hello_World!). Can anyone give me a better approach for this issue? Thanks in advance.
Current HTML code:
<nav class="navbar navbar-default">
<div class="container-fluid">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand logo-container" href="#"><img class="logo" alt="Logo" src="images/test.png" /></a>
</div>
<div class="collapse navbar-collapse" id="myNavbar">
<ul class="nav navbar-nav navbar-right">
<li><span class="code">goto </span><span class="section-name">Hello_World!</span></li>
<li><span class="code">goto </span><span class="section-name">About_Me</span></li>
<li><span class="code">goto </span><span class="section-name">Life_Graph</span></li>
<li><span class="code">goto </span><span class="section-name">Skill_Trees</span></li>
<li><span class="code">goto </span><span class="section-name">Feat_Stacks</span></li>
<li><span class="code">goto </span><span class="section-name">Codetact_Me</span></li>
</ul>
</div>
</div>
</nav>
HERE IS MY FIDDLE...

Answer 1

If my understanding for your quesetion is correct you can use .row & .col to block menu to new row
<nav class="navbar navbar-default">
<div class="container-fluid">
<div class="row">
<div class="navbar-header col-sm-1">
...
</div>
<div class="col-sm-11">
<div class="collapse navbar-collapse" id="myNavbar">
...
</div>
</div>
</div>
</div>
</nav>
You can change col-md-xx to make it wider or smaller
