level
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 Bulma level, they will always be
                        vertically centered.
