@page {   margin: 1cm; }  @page :first {   margin: 2cm; } 

@page

The @page CSS at-rule is used to modify some CSS properties when printing a document.

Syntax

@page {   margin: 1cm; }  @page :first {   margin: 2cm; } 

Descriptors

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

You can't change all CSS properties with @page. You can only change the margins, orphans, widows, and page breaks 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.

Formal syntax

where <page-selector> = <pseudo-page>+ | <ident> <pseudo-page>*<page-margin-box> = <page-margin-box-type> '{' <declaration-list> '}'
