How to implement :not-in-viewport?

[phlegx]

Hi all!

How can I check if an object is not-in-viewport?

Thx

hi phlegx, you can use jquery is().

example:
if(jQuery('.section-3').is(':in-viewport')){
$('.section-3').addClass('active');
} else {
$('.section-3').removeClass('active');
}

Or simply use .not(':in-viewport')
