Bug: html.Div and dbc.Row output does not vertically align

EDIT: I thought I had double-checked this before posting, but the problem I reported was definitely caused by my own:

.row {
  margin: 0;

modification required to solve Bug: Horizontal browser play using dbc.Row - #4 by AnnMarieW

So if that one can get solve properly with some other css adjustment then this would be solved too :neutral_face:
