Size
All size properties can be expressed in pixels (px), percentage (%), viewport width (vw), and viewport height (vh). Additionally, for Width and Height properties, the “auto” option is added.

Position Type
It determines if at the time of execution the element remains fixed on the page or if it moves as the scroll bar moves forward or backward.
Possible Values
•Default: The element has a relative position with respect to the superior element where it was placed (container or section).
•Fixed: Fixes the element to the page so that it is always visible in the same position. It allows to increase the visibility of important content.
Docking
Determines the vertical and horizontal position of elements within the page section or container, when the screen is resized.
When an element is added or moved within the section or container, the modeler automatically docks it to the nearest corners or edges. It can also be configured by clicking on the arrows of the side to be docked to or on the center.
Once the element is docked, its exact position is indicated in the Margins property. The direction of the docking arrows determine the values that are automatically displayed for margins.
The docking position is indicated in the modeling area by dotted lines on the element.
