Javascript close pop up div -

i have div hide/show onclick adds or removes css class. want able close/hide div when user clicks outside div area.

how do this? thanks!

i think you're looking can done javascript. event called 'onblur' triggers event handler when loses focus (e.g. div).

you can read more here: http://www.w3schools.com/jsref/event_onblur.asp

basically call javascript function when object loses focus:

onblur="myfunction();" 

...and 'myfunction()' have javascript change css.
