The right CSS property participates in specifying the horizontal position of a positioned element. This {{glossary("inset properties", "inset property")}} has no effect on non-positioned elements.

anchor() function values), and the {{cssxref("anchor-size()")}} function resolves to a {{cssxref("<length>")}} value relative to the associated anchor element's width or height (see Setting element position based on anchor size).{{cssxref("<percentage>")}}
auto
width: auto is treated as a width based on the content; or if left is also auto, the element is positioned where it should horizontally be positioned if it were a static element.left is also auto, the element is not moved horizontally at all.The effect of right depends on how the element is positioned (i.e., the value of the {{cssxref("position")}} property):
position is set to absolute or fixed, the right 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 an {{cssxref("anchor()")}} function, right positions the right edge of the positioned element relative to the specified <anchor-side> edge. The right property is compatible with the left, right, start, end, self-start, self-end, center, and <percentage> values.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 is used to compute the sticky-constraint rectangle.position is set to static, the right property has no effect.When both {{cssxref("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.

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.
