@page.bleed

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.

Related at-rule	`@page`
Initial value	`auto`
Media	as each of the properties of the shorthand: `visual`: Value not found in DB! `paged`: Value not found in DB!
Computed value	as specified
Canonical order	the unique non-ambiguous order defined by the formal grammar

Syntax
