marks - CSS: Cascading Style Sheets 编辑

Experimental

The marks CSS at-rule descriptor, used with the @page at-rule, adds crop and/or cross marks to the presentation of the document. Crop marks indicate where the page should be cut. Cross marks are used to align sheets.

Crop marks and cross marks are printed outside the page box. To have room to show crop and cross marks, the final pages will have to be somewhat bigger than the page box.
