background-position Redirect 1


The background-position CSS property sets the initial position, relative to the background position layer defined by background-origin for each defined background image.

Note: If the value of this property is not set in a background shorthand property that is applied to the element after the background-position CSS property, the value of this property is then reset to its initial value by the shorthand property.

  • Initial value 0% 0%
  • Applies to all elements
  • Inherited no
  • Percentages refer to the size of the background positioning area minus size of background image; size refers to the width for horizontal offsets and to the height for vertical offsets
  • Media visual
  • Computed value a list, each item consisting of two keywords representing the origin and two offsets from that origin, each given as an absolute length (if given a <length>), otherwise as a percentage
  • Animatable yes, as a repeatable list of a simple list of a length, percentage or calc(); when both values are lengths, they are interpolated as lengths; when both values are percentages, they are interpolated as percentages; otherwise, both values are converted into a calc() function that is the sum of a length and a percentage (each possibly zero), and these calc() functions have each half interpolated as real numbers.
  • Canonical order the unique non-ambiguous order defined by the formal grammar


Formal syntax:  <position>#


Is a <position>, that is one to four values representing a 2D position regarding the edges of the element's box. Relative or absolute offsets can be given. Note that the position can be set outside of the element's box.
