css at-rules "@page"

The @page at-rule is a CSS at-rule used to modify different aspects of a printed page property. It targets and modifies the page's dimensions, page orientation, and margins. The @page at-rule can be used to target all pages in a print-out, or even specific ones using its various pseudo-classes.

Syntax

/* Targets all the pages */
@page {
  size: 8.5in 9in;
  margin-top: 4in;
}

/* Targets all even-numbered pages */
@page :left {
  margin-top: 4in;
}

/* Targets all odd-numbered pages */
@page :right {
  size: 11in;
  margin-top: 4in;
}

/* Targets all selectors with `page: wide;` set */
@page wide {
  size: a4 landscape;
}

Descriptors

page-orientation

Specifies the orientation of the page. This does not affect the layout of the page; the rotation is applied after the layout in the output medium.

size

Specifies the target size and orientation of the page box's containing block. In the general case, where one page box is rendered onto one page sheet, it also indicates the size of the destination page sheet.

Description

Note: This documentation lists out features yet to be implemented across UAs, but they are stated in the official documentation. At the time of this writing, the only CSS property shown to have visible on both the at-rule and its pseudo-classes is the margin property.

You can't change all CSS properties with @page. You can only change the margin of the document. Attempts to change any other CSS properties will be ignored.

The @page at-rule can be accessed via the CSS object model interface CSSPageRule.

Note: The W3C is discussing how to handle viewport-related <length> units, vh, vw, vmin, and vmax. Meanwhile do not use them within a @page at-rule.

Related properties

The @page at-rule, allows the user to assign a name to the rule, which is then called in a declaration using the page property.

margin at-rules

The margin at-rules are used inside of the @page at-rule. They each target a different section of the document printed page and make changes based on the properties or content set in the block of code:

@page {
  @top-left {
    <page-margin-properties>
  }
}

@top-left targets the top-left of the document and applies the changes based on the page-margin-properties set.

Other margin-at rules include:

@top-left-corner {
  <page-margin-properties>
}
@top-left {
  <page-margin-properties>
}
@top-center {
  <page-margin-properties>
}

Named pages

Named pages enable performing per-page layout and adding page-breaks in a declarative manner when printing.

Named pages can be applied using the page property. This allows the user to create different page configurations for use in print layouts.

An example of this can be found on the page examples.

Examples

Using the size property to change the page orientation

This example shows how to split the <section>s into individual pages in landscape format with each page having a 20% margin when printed.
