The right CSS property participates in specifying the horizontal position of a positioned element. It has no effect on non-positioned elements.

/* <length> values */
right: 3px;
right: 2.4em;

/* <percentage>s of the width of the containing block */
right: 10%;

/* Keyword value */
right: auto;

/* Global values */
right: inherit;
right: initial;
right: unset;

The effect of right depends on how the element is positioned (i.e., the value of the position property):

  • When position is set to absolute or fixed, the right property specifies the distance between the element's right edge and the right edge of its containing block.
  • When position is set to relative, the right property specifies the distance the element's right edge is moved to the left from its normal position.
  • When position is set to sticky, the right property behaves like its position is relative when the element is inside the viewport, and like its position is fixed when it is outside.
  • When position is set to static, the right property has no effect.

When both left and right are defined, the position of the element is overspecified. When this is the case, the left value has precedence when the container is left-to-right (thus, the computed value of right  is set to -left); the right value has precedence when the container is right-to-left (thus, the computed value of left is set to -right).

Syntax

Values

<length>
A negative, null, or positive <length> that represents:
  • for absolutely positioned elements, the distance to the right edge of the containing block;
  • for relatively positioned elements, the distance that the element is moved to the left of its normal position.
<percentage>
A <percentage> of the containing block's width.
auto
Specifies that:
  • for absolutely positioned elements, the position of the element is based on the left property, while width: auto is treated as a width based on the content.
  • for relatively positioned elements, the distance of the element from its normal position is based on the left property, or if left is also auto, the element is not moved horizontally at all.
inherit
Specifies that the value is the same as the computed value from its parent element (which might not be its containing block). This computed value is then handled as if it were a <length>, <percentage>, or the auto keyword.

Formal syntax

<length> | <percentage> | auto
