Button which is not rendered

Extracted from #34 (closed).

What is the purpose of this button?

• Button in navbar.component.html, der nicht gerendert wird:

<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#collapsibleNavbar">
    <span class="navbar-toggler-icon"></span>
</button>

mentioned in issue #34 (closed)

This button is a part of the bootstrap Navbar concept (https://getbootstrap.com/docs/4.0/components/navbar/).

I suspect that is not rendered, because not used in our context. It might be contraproductive to just delete it, because it might become relevant again, when we refactor the bootstrap design.
