Columns enable you to horizontally organise the content within your sections. They must be located under mj-section tags in order to be considered by the engine. To be responsive, columns are expressed in terms of percentage.
❗️ The Border Radius and Inner Border Radius parameters will only apply to background colours because of Outlook compatibility. If you’d like to add a selector to override this, add the following
.c-roundedtable,
.c-roundedtable>tr>td,
.c-roundedtable>tbody>tr>td
{ border-collapse:separate; }
as a Custom CSS Style block and then in your column under Styling/Custom CSS Classes add c-rounded. This will then apply it to your borders but might give unexpected behavior in Outlook.
