Removing or changing the gap between columns

By default, there is a 16px gap between the columns in multi-column layouts. (You can learn more about Legacy: Using Page Layouts with Slide Presenter).

If you want to change or remove this gap, add the following CSS to your theme:

.columnLayout .cell {
  padding-right: 0;
}

This instructs the theme to have no padding on all columns in a column layout. You can use other values than the 0 used in the example, for example you could use 32px to make the gap 32 pixels wide.
