You can add columns to the content of any post or page using the following shortcode:
[column size="one_half"]Your Content Goes Here[/column]
[column size="one_half" last="true"]More Content Goes Here[/column]
The column shortcode takes 2 parameters: size and last. You may select one_half, one_third, two_third, one_fourth, three_fourth, one_fifth, two_fifth, three_fifth, four_fifth, one_sixth or five_sixth for the size parameter. Don’t forget that the last parameter must be set to true for the last column in the row.
