margin-right
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The margin-right
CSS property sets the margin area on the right side of an element. A positive value places it farther from its neighbors, while a negative value places it closer.
Try it
The vertical margins of two adjacent boxes may fuse. This is called margin collapsing.
