Ok, thanks for useful replies. Last question:
I know that is not possible load dinamically "filename.css" for a iframe content. And so I need to put: <link rel=stylesheet href="filename.css"> in sample.html (page loaded in iframe). Do you know if exist a way to toggle/add/removeClass in jquery dinamically (css-class below for example) for iframe-elements? .hover { cursor: pointer; border-width: 3px; border-style: solid; border-color: #FF0000; } I tried to put this in main.html: $(frame).bind('mouseover', function(event) { var element = $(event.target); element.addClass('hover'); }) it works only if i put <link rel=stylesheet href="filename.css"> above in sample.html (or class above in <style />) is it possible create and load a class dinamically with jquery avoiding to modify sample.html??? Thanks, Julio
