I don't know exactly in what to place this, whether as a DOM method/property (?) or if it's more appropriate for this comes in handy for games, but also for regular DHTML for element positioning and page sizing. many times a web developer will make a page hard-coded for certain screen sizes, but knowing the document width and height, and being able to rework the document for that could be handy for some. may get popular. I know I could use these both. Example: <!--form controls for 4D--> <div id="o2" onresize="doresize()"><canvas id="c">4D canvas</canvas></div> <script> function doresize() { var formControls=document.getElementById('f').height; var nw=getElementById('nnavigation').width; var c=document.getElementById('c'); c.width = document.width - nw; c.height = document.viewport.height - formControls.height; } </script> 91136 1 kornel 2013-07-23 13:45:42 +0000 Have you tried requestAnimationFrame and window.onresize? 92876 2 robin 2013-09-03 13:21:34 +0000 EDITOR'S RESPONSE: This is an Editor's Response to your comment.

For more details, see this document: http://dev.w3.org/html5/decision-policy/decision-policy.html Status: Rejected Change Description: none Rationale: We already have onresize, and painting at the "right" frequency can already be done with requestAnimationFrame().
