Hi, I would like to know if there is a way how PHP code can extract from ElementID some property values. for example, i have the following PHP page : <?php print "<div class='maindiv' id='id_maindiv'>my main div</div>"; $new_Width = somefunction(); print "<div class='childdiv' id='id_childdiv' style='width:".$new_Width."px;'>my child div</div>"; ?> in my CSS file (which is link to my HTML page), i have : .maindiv { width : 300px; height : 400px; background-color : #EEBBEE; } .childdiv { background-color : #BBBBBB; } my PHP code should be able : - to extract the width of id_maindiv ID (so to get 300px) and to reduce it by 50px the problem is that i tried with Javascript and if the property (style:width) is not define DIRECTLY to HTML code (but only in CSS file), the javascript is not able to return the value (but only 'undefined'). So i would like to know if PHP could help me in this way ? thanks a lot, -- Alain ------------------------------------ Windows XP SP2 PostgreSQL 8.1.4 Apache 2.0.58 PHP 5
