javascript - CSS/Jscript height problems -

-

i trying make grid of squares updates size of window. using following js code this:

$(window).ready(updateheight); $(window).resize(updateheight);  function updateheight() {     var div = $('.grid');     var width = div.width();;     div.css('height', width);      var ratio=14.3/126;     div = $('.face');     width = div.width();;     div.css('height', width+(ratio*width));      ratio=30.5/15;     div = $('.cubie');     width = div.width();;     div.css('height', width+(ratio*width)); };

the cubies nested inside faces, nested inside grid in html. first tried setting height with

div.css('height', width)

..but reason didn't make faces , cubies square. ratio thing helps correct on screen size, smaller make window more noticeable error becomes, i'm searching different solution right now, , cant seem find one. appreciated.

ps: if matters, .grid width 50% of body, .face 20% of .grid, , .cubie ~33% of that.
