Firefox 3.6 (win)
Safari 5.0 (win)
Opera 11.0 (win)
IE9
IE8
IE7
IE6
Android

HISTORY:
1.3 - Added tests for CSS3 properties
1.2.3 - Bug Fix - added ; at  end of object declarations
1.2.2 - Added multiple image Loader
1.2.1 - Added Single Image Loader
1.1 - Added XML Loader / Parser
1.0 - initial version

ISSUES:
Testing for column-count in Opera returns wrong value


CONTENTS:

setBoundInterval - when you need to call setInterval bound to a specific object (not the window)

	SKYLARK.setBoundInterval(function:Function, duration:Number, bind:Object):Number

testFor.placeholder - first of a number of tests.  This ones tests for support of placeholder attribute (used by form.js)

	SKYLARK.testFor.placeholder():Boolean
	
Load.xml - loads XML file via xmlhttprequest and parses it into a js object

	SKYLARK.Load.xml(url:String, callback:Function):Object

Chrome 8/.0
Firefox 3.6
IE 9

Opera 10.63

HISTORY:

USAGE

1) Add the attribute validate="yes" to the FORM tag
2) Add the attribute validation="[type_of_validation]" to the form field tag
3) To send the form you must add a listener to the form's 'validationPassed' event, eg..

$('form').bind('validationPassed', function(){
	this.send();											
});

4) to set a custom error message and the attribute errorMessage="your_message_here" to the form field tag

Validation Types:

required
email
url
matches (matches to regexp)
