I have the following code, which fades in HTML via a .load into a .pop-up modal.
$('.about').click(function(){
    $('.pop-up').load('about.php', function(){
        $(this).fadeIn();
    });
However, I need a second click to make the .about fade out. I understand certain toggle functions are now deprecated. Is there a current method I could use? I have a couple of these functions which will need toggling throughout the code.
Any help would be great.
