iFrame height problem

I have a VisualForce page which loads using a standardController.


After  loading the parent page, the child page loads with the following iframe:

<iframe frameborder="no" height="200px" id="066A0000001LEZa" marginheight="0" marginwidth="0" name="066A0000001LEZa" scrolling="no" title="activitiesnewlayout" width="100%"></iframe>


Here's the body syntax embedded in the iFrame

<body onload="if (this.bodyOnLoad) bodyOnLoad();" onbeforeunload="if (this.bodyOnBeforeUnload) {var s =bodyOnBeforeUnload(); if (s) return s;}" onunload="if (this.bodyOnUnload) bodyOnUnload();" onfocus="if (this.bodyOnFocus) bodyOnFocus();" class="Custom41Tab  apexPageInline sfdcBody" marginwidth="0" marginheight="0">


I have tried multiple ways to modify the hight of that iFrame using javascript, css, div in the VisualForce child page, none of them worked, till i noticed that the child page does not execute any javascript commands, even <body style="background:red" onLoad="javascript&colon;alert(123);"> , the background goes red but no alert pops out since the child page onLoad cannot override the main one loaded by default..


I viewed both related threads and with no solution


Anyone advise plz? Is theere anyone that i can add some code to that onLoad syntax or override it?
