Optional

Fifth video of the series on the design system for the frontend. Here is a detailed overview, to show the fundamental importance of controls and classes. 
It explains how to use static, relative, and absolute positions, together with the properties Top, Bottom, Left, and Right of control classes. Also, an example of overlapping using Margin Top is included. Its pros and cons are described. All this is based on the frontend panels for Travel Agency.
(Note: after GeneXus upgrade 7, the overlap will be very simple, using the Canvas control, which already existed for Smart Devices but not for Web)
Examples of use of the Flex control are provided, and it is compared with tables.
