how to alter load state of a slider

i had a form with a checkbox and a slider.
I have added these two event in my checkbox:
= checked show chronoforms-container-4
!= uncheck hide chronoforms-container-4

the events works , but i dont want the slider shown when the form is loaded, because i must check /uncheck the checkbox once to hide it.
Is there a way to hide the slider directly when my form loads?

I ask this because there is no load state for the container.
so i try jquery but there is some conflicts with the events.... and the events dont work...

If the load state is ok for the next version, i will wait...
if someone have a solution, this should help me and a lot more people.
Thanks by adavnce

This worked for me in default load state pf contaner, "#pag_envio" is my id div container
i set in custom code before HTML(render form)

<?php
 $css = array();
   $css[] = '#pag_envio{ display: none; }';
 $doc =& JFactory::getDocument();
 $doc->addStyleDeclaration($css);
 ?>
