Experimental

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The bleed CSS at-rule descriptor, used with the @page at-rule, specifies the extent of the page bleed area outside the page box. This property only has effect if crop marks are enabled using the marks property.

Syntax

/* Keyword values */
bleed: auto;

/* <length> values */
bleed: 8pt;
bleed: 1cm;

Values

auto

Computes to 6pt if the value of marks is crop. Otherwise it computes to zero.

<length>

Specifies by how far outward, in each direction, the bleed area extends past the page box. Values may be negative, but there may be implementation-specific limits.

Formal definition

Formal syntax
