/* Workaround for sidebar issues, especially together with toggle buttons:
   If we place toggle admonition next to a sidebar, the layout will be messed
   up. By adding this class to the admonition box (if it's an exercise-solution
   pair, the exercise admonition), we enforce vertical space that pushes the
   admonition after the sidebar.
