Visual Composer row settings allow to set all columns within a row to have the same height. The height of the columns will be similar to the column with the longest content.
To set an equal height for all columns:
- Open row edit window
- Enable "Column equal height" toggle
- All columns in a row are now equal in height
In addition to equal columns height, you can also manipulate with content vertical position. By default, the content is placed on the top, but you can align content vertically in the middle or stick to the bottom of the columns.
