  <p>and here is the code of the page index.html</p>
  
  <pre><code> &lt;!Doctype html&gt;
  &lt;html&gt;
  
  &lt;head&gt;
      &lt;meta charset="utf-8" /&gt;
      &lt;meta name="viewport" content="width=device-width,initial-scale=1.0" /&gt;
      &lt;meta name="description" content="description here"/&gt;
      &lt;meta name="author" content="author's name and contact" /&gt;
      &lt;link rel="stylesheet" href="./node_modules/bootstrap/dist/css/bootstrap.min.css" /&gt;
      &lt;title&gt;Bienvenue a TSL Group&lt;/title&gt;
  &lt;/head&gt;
  
  &lt;body&gt;
      &lt;div class="container"&gt;
          &lt;div class="row"&gt;
              &lt;nav class="navbar navbar-default" role="navigation"&gt;
                  &lt;div class="navbar-header"&gt;
                      &lt;a class="navbar-brand"&gt;Brand name&lt;/a&gt;
                  &lt;/div&gt;
                  &lt;div class="navbar-collapse collapse navbar-right"&gt;
                      &lt;ul class="nav navbar-nav"&gt;
                          &lt;li&gt;
                              &lt;a href=""&gt;welcome&lt;/a&gt;
                          &lt;/li&gt;
                          &lt;li&gt;
                              &lt;a href=""&gt;Products&lt;/a&gt;
                          &lt;/li&gt;
                          &lt;li&gt;
                              &lt;a href=""&gt; Services&lt;/a&gt;
                          &lt;/li&gt;
                          &lt;li&gt;
                              &lt;a href=""&gt;Menu &lt;/a&gt;
                          &lt;/li&gt;
                          &lt;li&gt;
                              &lt;a href=""&gt;Contact us&lt;/a&gt;
                          &lt;/li&gt;
                      &lt;/ul&gt;
                  &lt;/div&gt;
              &lt;/nav&gt;
          &lt;/div&gt;
      &lt;/div&gt;
  &lt;/body&gt;
  &lt;script type="text/javascript" src="./node_modules/jquery/dist/jquery.min.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="./node_modules/bootstrap/dist/js/bootstrap.min.js"&gt;
  &lt;/script&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>But unfortunately, when I run the page in the browser, the navbar is not displayed. I don't know what is wrong with this code.
  Any help?</p>
