Right
Right is used to help to specify the position for positioned elements.
The other positioning properties are bottom,top , and left.
For elements that are absolutely positioned, right specifies the distance between the right margin edge of the element
and the right of its containing block.
For elements that are relatively positioned, it specifies how far the element is moved left of its normal position.
Negative values mean that the element is moved right rather than left.
The options are:
(1) Auto, the default value, it means the browser will calculate the position.
(2) Length, allows you to set the value as a fixed length, for example in px or cm.
(3) Percentage, allows you to set the value as a percentage of the containing elements height.
(4) Inherit, the value is inherited from its parent element.
