Close a div by clicking outside

An other way which makes then your jsfiddle less buggy (needed double click on open).

This doesn’t use any delegated event to body level

Set tabindex="-1" to DIV .popup ( and for style CSS outline:0 )

DEMO

$(".link").click(function(e){
    e.preventDefault();
    $(".popup").fadeIn(300,function(){$(this).focus();});
});

$('.close').click(function() {
   $(".popup").fadeOut(300);
});
$(".popup").on('blur',function(){
    $(this).fadeOut(300);
});
