The margin is the space between this element and other elements that will be adjacent when layout creates the user interface (UI). Shared elements might be peer elements (such as other elements in the collection of a common parent control), or might also be this element's parent.
is set as a Thickness structure rather than as a number so that the margin can be set asymmetrically. The Thickness structure itself supports string type conversion so that you can specify an asymmetric in XAML attribute syntax also.
Margins are additive for sibling elements in a layout; for example, two adjacent elements both with a margin of 30 set on the adjoining edge would have 60 units of space between them.
Elements that have margins set will not typically constrain the size of the specified if the allotted rectangle space is not large enough for the margin plus the element content area. The element content area will be constrained instead when layout is calculated. The only case where margins would be constrained also is if the content is already constrained all the way to zero.
