TILES are "variable height":
- Are part of a flex-box row
- Height of a tile is based on the content / formatter
- All tiles in a row will have the same height decause of flex
- If height of tiles on a row is variable, flex will compensate for this
SQUARES require "fixed height":
- Are not in flex-box row, use traditional box model
- Usually do "float" left
- Height must be set in the square itself as fixed height
