工具提示显示困难

I'm trying to resolve a problem that I encountered with the creation of a tooltip interface in a website I'm developing. I constructed the tooltips with help of HTML, CSS and JavaScript. The script is pretty simple as you can see in the fiddle underneath, and is based on a toggle behaviour, on witch a trigger element open a pop-up tooltip.

Now! My problem is that i can't figure out how to place the trigger on the top of everything so they are not hidden by the pop-ups! Let me explain. Since the pop-up, even when they are off, sometimes cover the trigger elemets they (the triggers) just result not clickable. is like they are hidden behind invisible pop-ups. Here is a link of how is right now online.

I hope you can see the problem! Does anyone know how to resolve this?

You've changed the .pop-ups to "block" as soon as it initializes. $("div.pop-up").css({'display':'block','opacity':'0'})

If you want to show/hide, I would recommend using .fadeIn/.fadeOut: http://api.jquery.com/fadein/
