Spacer

Explicit vertical whitespace.

A spacer adds explicit vertical space between blocks. It's a single line; no closing ::: needed:

Above the gap.

::: spacer 48

Below the gap.

The number is the height in pixels; other CSS units work too (::: spacer 2em). Without a value the spacer is 24px:

::: spacer

Spacers work inside columns as well:

:::: columns
::: column
Top of the column

::: spacer 40

Pushed down
:::
::: column
Other column
:::
::::

Spacers leave no trace in the plain-text version of the email.
