Seems like this change made it inconsistent, fx-row generates with the div, but fx-col without the div
#56
plus
if it is without the <div infront, why it does have > in the end since the request was to be only attributes. Like this change is incompleted

<div fxLayout="row" fxLayoutAlign="start start" fxLayoutGap="gappx">
  
</div>

vs

fxLayout="column" fxLayoutAlign="start start" fxLayoutGap="gappx">
