Good job! Can you please explain how to use the cards?
For example:
HorizontalLayout card5 = new HorizontalLayout();
card5.setStyleName(MaterialTheme.CARD_5);
card5.addComponent(new Label(“Hello World”));

shows only the label…no card…

Three possibilities:

  1. Incorrect import of the theme
  2. Old browser cache
  3. You did not compile the theme.
