For absolutely positioned elements, the right property sets the right edge of an element to a unit to the left or right of the right edge of its containing element. For relatively positioned elements, the right property sets the right edge of an element to a unit to the left or right of its normal position. Negative values are allowed.
Note: the way an element moves on screen when you apply a positive 'right' value may seem counterintuitive. It moves left on the screen when given a positive value because the browser increases the distance between the right of the element and some reference point. If in doubt, just look at the direction of the icon. The icon depicts the direction the element will move on the page as you increase the value for 'right'.

e.g. '20' would move an element 20 pixels to the left of the right edge of its parent element (if the element is absolutely positioned), or 20px to the left of it's normal position (if the element is relatively positioned)
