CSS top

CSS top property decides the top offset for positioned elements. An element is considered positioned if its position property has value other than static.

CSS property top

CSS version: CSS 2.1
Value: length | percentage | auto | inherit
Initial: auto
Applies to: positioned elements
Inherited: no

  1. property top can be applied to positioned elements (fixed, relative, absolute)
  2. For absolute element the offset is relative to nearest positioned container.
  3. For relative element the offset is relative to the element’s normal position itself.
  4. In case value is specified as percentage, it is percentage of containing block width.
  5. Negative values are ok.
