The structure of a level is the following:
- 
          
level: main containerlevel-leftfor the left side- 
              
level-rightfor the right sidelevel-itemfor each individual element
 
 
In a level-item, you can then insert almost anything you want: a title, a button, a text input, or just simple text. No matter what elements you put inside a Elenore level, they will always be vertically centered.
