:right

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The :right CSS pseudo-class, used with the @page at-rule, represents all right-hand pages of a printed document.

css

/* Selects any right-hand pages when printing */
@page :right {
  margin: 2in 3in;
}

Whether a given page is "left" or "right" is determined by the major writing direction of the document. For example, if the first page has a major writing direction of left-to-right then it will be a :right page; if it has a major writing direction of right-to-left then it will be a :left page.

Note: This pseudo-class can be used to change only the margin, padding, border, and background properties of the page box. All other properties will be ignored, and only the page box, not the document content on the page, will be affected.
