Use css instead of javascript to show/hide divs

[violina]

Hi. As you all may know we can show and hide divs with javascript functions, but in my case i need to show and hide divs in a newsletter, and by default javascript is not enabled in email messages. So my question is whether it is possible to use only css or some other techniques instead of javascript, so i don't have to charge all the recipients of the newsletter to enable javascripts in their email accounts.
thanks in advance )

The css that you can use in e-mail is only at inline level, so you can't manage hover states.
