Syntax

top: { length | percentage | auto | inherit } ;

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.

Negative values are allowed and would result in the element being moved in the opposite direction to those already stated above.

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;
}

Internet Explorer for Windows versions up to and including 6:

  • compute percentage values on the basis of the height of the parent block, rather than of the containing block
  • don’t support the specification of both the position and the dimensions of an absolutely positioned element using top, right, bottom, and left together; they’ll use the last vertical and horizontal position specified, and need the dimensions to be specified using width and height

Internet Explorer for Windows versions up to and including 7 don’t support the value inherit.
