How to make dropdown navbar black? - html

Question

I'm trying to make dropdown navbar box black, I've been looking for solution for 2 days, but still even templates from bootstrap docs doesn't work properly, I mean that dropdown box.
Here is my html code for navbar:
<nav class="navbar navbar-inverse navbar-static-top">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navcol-1">
<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 navbar-link"><img src="/images /logo.png"></a>
</div>
<div class="collapse navbar-collapse" id="navcol-1">
<ul class="nav navbar-nav navbar-right">
<li role="presentation">Main </li>
<li role="presentation">Main </li>
<li role="presentation">Main </li>
<li role="presentation">Courses </li>
<li role="presentation">Help
<a class="visible-sm-block" href="#"> </a>
</li>
</ul>
</div>
</div>
</nav>

You're correctly using .navbar-inverse, which should already be making your navbar black, as can be seen here.
There are a couple of reasons why this may not be working for you.
You've not referenced Bootstrap correctly.In this case, check for errors in your F12 Developer Tools' console.
You're using CSS for a different version of Bootstrap than the one you've loaded.
You have code that is overriding the defaults with higher specificity.
You have cached outdated CSS. Refresh your stylesheet refrence with CTRL + F5, and hold SHIFT while clicking on the refresh icon to ensure you clear your CSS cache as well.
Hope this helps! :)
