### Expected solution

In the best case:

* The elements (toolbar, content elements) handle the shrink behavior themselves without a breakpoint. 
* (Take care that this also works with with a resizing menu)
* If the elements cannot shrink any more they should get a scroll bar which lets them scroll and not the whole page.

In the worst case:

* We need to add a tablet screen sized breakpoint and handle the styling there separately like we do it for mobile.End of the insertion
