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):
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.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.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.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
).
