Visual Composer root shortcode container
“Row“ is the main content element of Visual Composer. Rows are used to divide your page into the logic blocks with columns, columns later will hold your content blocks. Rows can be divided into the layouts (eg. 1/2 + 1/2, 1/3 + 1/3 + 1/3, and so on). Your page can have unlimited number of rows. To change row's position, click and drag row's drag handler (top left row's corner) and drag row around (vertical axis).
