Example
This style rule makes the element
with ID "logo" generate a relatively positioned box
that’s shifted down by ten pixels:
#logo {
position: relative;
top: 10px;
}Description
For absolutely positioned
boxes, this property specifies how far the top margin edge of the box is
offset below the top padding edge of its containing block. However, should
the value for top be auto (the
initial value), the top margin edge of the box will be positioned at the
top content edge of its containing block.
For relatively positioned boxes, this property specifies how far the top edge of the box is offset below the position it would have had in the normal flow.
