We agree with this proposal.  We think it would better clarify page break behavior.   *************************************************************************** Don Wright                     don@lexmark.com                                f.wright@ieee.org / f.wright@computer.org Director of Standards Lexmark International          INCITS Executive Board Vice-Chair C14/082-3                      IEEE SA Standards Board Past Chair 740 New Circle Rd              IEEE SASB Patent Committee Chair   Lexington, Ky 40550            Member: IEEE SA Board of Governors 859-825-4808 (phone)           Member: IEEE CS SAB & W3C AC 603-963-8352 (fax)             Director, IEEE-ISTO ***************************************************************************   <table width=100%> <tr valign=top> <td> <td>"Grant, Melinda" <melinda.grant@hp.com> Sent by: owner-xp@pwg.org 09/13/2006 10:21 PM <td>                To:        <xp@pwg.org>         cc:                 Subject:        XP> [CSS3 Paged Media] Page collapsing</table> The CSS Paged Media specification (<a href="http://www.w3.org/TR/2004/CR-css3-page-20040225/">http://www.w3.org/TR/2004/CR-css3-page-20040225/</a>) is currently unclear as to what should happen when multiple page-break-* properties accumulate.  The spec is clear that a :left or :right pseudo-class can require that a blank page or surface is generated.   For example: This is a paragraph on page 1. <div style="page-break-before">     <div style="page-break-before">         The first div causes a page break; does the second div cause another page break, putting this content on page 3, or are the page breaks collapsed into a single page break so that this is printed on page 2?</div> </div> Or: <body>   I am printed on the first page.  <div style="page-break-after:always">    <div style="page-break-after:always">      <div style="page-break-after:always">        <div style="page-break-after:always">          <div style="page-break-after:always"> I am also printed on the first page.          </div>        </div>      </div>    </div>  </div>  Where am I printed? </body> Or: <body> This is a paragraph on page 1. <div style="page-break-before">         The p generated a page break; does the div cause another page break, putting this content on page 3, or are the page breaks collapsed into a single page break so that this is printed on page 2? </div> </body> Different implementations behave differently, as might be expected.  I would like to tighten up the spec to require that page-break properties collapse such that no empty pages or surfaces are generated except for one when needed to get to the next right- or left-facing page.  Authors can use other means to create blank pages.  This will make results more interoperable.   (I do not yet have consensus from the CSS WG to make this change.  Most implementations collapse pages, but Opera's does not, and they may not be willing to accept the change.)   If you wish to object to this proposed clarification or express support, please do so by posting a response here or to <a href="mailto:www-style@w3.org">www-style@w3.org</a> by September 23.   Best wishes,   Melinda  _____ HP  -   Melinda Grant Connectivity Standards Consumer Printing and Imaging +1 (541) 582-3681 melinda.grant@hp.com    _____
