Twitter Bootstrap Question posted in

Twitter bootstrap navbar-inverse class doesn't make navbar inverse, and prevents links from appearing

I have built a simple webpage using Twitter Bootstrap, and I have 2 problems:

  1. Although I have given the navbar a class of navbar-inverse, it just appears as a white rectangle and looks no different to the rest of the webpage. Divs with a class of navbar-inverse are supposed to have inverse colours: a dark background-color, and light text.
  2. I have three links with an empty href, but they don’t appear. They still don’t appear if I give them a href of #.

Here is a link to the result I am getting: http://jsbin.com/poqofapiqa/edit?html,output

    Navbars:

    Use the navbar-dark and bg-dark classes instead:
    <nav class="navbar navbar-dark bg-dark"><!-- Navbar content --></nav>

    Links:

    Use at least <a href="#">...</a> , not blank href attribute.
    Anchors with blank attributes interpreted as usual (non-link) elements

    <!doctype html>
<html lang="en">
  <head>
    <title>Hello, world!</title>
    <!-- Required meta tags -->
    <meta charset="utf-8">

    You are using it in a wrong way. Class nav-collapse is used to display mobile menu button. The content available in nav-collapse will not be shown on webpage.
    You can use this code for your menu.

    <!DOCTYPE html>
<html lang="en">
<head>
  <title>Bootstrap Example</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">

  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>
<body>

<nav class="navbar navbar-inverse">
  <div class="container-fluid">
    <div class="navbar-header">
      <a class="navbar-brand" href="#">WebSiteName</a>
    </div>
    <ul class="nav navbar-nav">
      <li class="active"><a href="#">Home</a></li>
      <li><a href="#">Page 1</a></li>
      <li><a href="#">Page 2</a></li>
      <li><a href="#">Page 3</a></li>
    </ul>
  </div>
</nav>
