Theming: Whitespace

Properties

Whitespace can be applied using three different properties: Margin, Padding and Spacing.

If you use HorizontalLayout or VerticalLayout you can use setMargin(true), setPadding(true) and setSpacing(true).

However, these methods aren’t available for Div, FlexLayout or any other container. The Business App Starter enables you to apply margin, padding and spacing on any Component using class names.

Sizes

There are five different sizes: XS, S, M (default), L and XL.

Directions

And nine different directions: BOTTOM, LEFT, RIGHT, TOP, HORIZONTAL, VERTICAL, TALL, UNIFORM (default) and WIDE.

Example

Use the following formula to apply margin, padding, or spacing: component.addClassName(LumoStyles.<PROPERTY>.<DIRECTION>.<SIZE>).

Example 1

Source code
Java
component.addClassName(LumoStyles.Padding.Uniform.M);

Example 2

Apply multiple styles at once using addClassNames:

Source code
Java
component.addClassNames(
  LumoStyles.Margin.Horizontal.XL
  LumoStyles.Padding.Vertical.XL,
  LumoStyles.Spacing.Bottom.M
);
