Example 

                    
                      <nav aria-label="breadcrumb">
                        <ol class="breadcrumb">
                          <li class="breadcrumb-item active" aria-current="page">Home</li>
                        </ol>
                      </nav>

                      <nav aria-label="breadcrumb">
                        <ol class="breadcrumb">
                          <li class="breadcrumb-item"><a href="#">Home</a></li>
                          <li class="breadcrumb-item active" aria-current="page">Library</li>
                        </ol>
                      </nav>

                      <nav aria-label="breadcrumb">
                        <ol class="breadcrumb">
                          <li class="breadcrumb-item"><a href="#">Home</a></li>
                          <li class="breadcrumb-item"><a href="#">Library</a></li>
                          <li class="breadcrumb-item active" aria-current="page">Data</li>
                        </ol>
                      </nav>

                      <nav aria-label="breadcrumb">
                        <ol class="breadcrumb breadcrumb-light">
                          <li class="breadcrumb-item"><a href="#">Home</a></li>
                          <li class="breadcrumb-item"><a href="#">Library</a></li>
                          <li class="breadcrumb-item active" aria-current="page">Data</li>
                        </ol>
                      </nav>

Changing the separator

Separators are automatically added in CSS through ::before and content . They can be changed by changing $breadcrumb-divider. The quote function is needed to generate the quotes around a string, so if you want > as seperator, you can use this:

              
                $breadcrumb-divider: quote(">");

It's also possible to use a base64 embedded SVG icon:

              
                $breadcrumb-divider: url(data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHdpZHRoPSI4IiBoZWlnaHQ9IjgiPjxwYXRoIGQ9Ik0yLjUgMEwxIDEuNSAzLjUgNCAxIDYuNSAyLjUgOGw0LTQtNC00eiIgZmlsbD0iY3VycmVudENvbG9yIi8+PC9zdmc+);

The separator can be removed by setting $breadcrumb-divider to none:

              
                $breadcrumb-divider: none;
