right
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The right
CSS property participates in specifying the horizontal position of a positioned element. This inset property has no effect on non-positioned elements.

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 anchor-positioned elements, the
anchor()
function resolves to a<length>
value relative to the position of the associated anchor element's left or right edge. - 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, whilewidth: auto
is treated as a width based on the content; or ifleft
is alsoauto
, the element is positioned where it should horizontally be positioned if it were a static element. - for relatively positioned elements, the distance of the element from its normal position is based on the
left
property; or ifleft
is alsoauto
, the element is not moved horizontally at all.
- for absolutely positioned elements, the position of the element is based on the
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 theauto
keyword.
Description
The effect of right
depends on how the element is positioned (i.e., the value of the position
property):
- When
position
is set toabsolute
orfixed
, theright
property specifies the distance between the element's outer margin of right edge and the inner border of the right edge of its containing block. If the positioned element has an associated anchor element, and the property value includes ananchor()
function,right
positions the right edge of the positioned element relative to the specified<anchor-side>
edge. Theright
property is compatible with theleft
,right
,start
,end
,self-start
,self-end
,center
, and<percentage>
values. - When
position
is set torelative
, theright
property specifies the distance the element's right edge is moved to the left from its normal position. - When
position
is set tosticky
, theright
property is used to compute the sticky-constraint rectangle. - When
position
is set tostatic
, theright
property has no effect.
When both left
and right
are defined, if not prevented from doing so by other properties, the element will stretch to satisfy both. If the element cannot stretch to satisfy both — for example, if a width
is declared — the position of the element is over-constrained. When this is the case, the left
value has precedence when the container is left-to-right; the right
value has precedence when the container is right-to-left.

Percentages | refer to the width of the containing block |
Computed value | if specified as a length, the corresponding absolute length; if specified as a percentage, the specified value; otherwise, auto |

Examples
Absolute and relative positioning using right
HTML
<div id="relative">Relatively positioned</div>
<div id="absolute">Absolutely positioned</div>
CSS
#relative {
width: 100px;
height: 100px;
background-color: #ffc7e4;
position: relative;
top: 20px;
left: 20px;
}
#absolute {
width: 100px;
height: 100px;
background-color: #ffd7c2;
position: absolute;
bottom: 10px;
right: 20px;
}
Result
Declaring both left and right
When both left
and right
are declared, the element will stretch to meet both, unless other constraints prevent it from doing so. If the element will not stretch or shrink to meet both. When the position of the element is overspecified, the precedence is based on the container's direction: The left
will take precedence if the container's direction is left-to-right. The right
will take precedence if the container's direction is right-to-left.
HTML
