Using jQuery to animate the opacity to 0 and then smoothly fade out the element

I am currently working on a function that animates the opacity of an element to 0 as the user scrolls. However, I am facing an issue where the element is fading out too early instead of waiting for the animation to finish. Here is a link to my jsFiddle showcasing the problem: http://jsfiddle.net/6hcm4qg4/

Here is the code snippet from my markup:

$(window).scroll(function() {
  var scrollTop = $(window).scrollTop();
  var height = $(window).height();

  var myEvent = function() {
    $('.logo_container, .slogan').css({
      'opacity': ((height - scrollTop) / height)
    });
  };
  
  $.when(myEvent()).done(function() {
    $('.logo_container, .slogan').fadeOut();
  });

});

If anyone has any suggestions or fixes for this issue, I would greatly appreciate it!

If you want to create a smooth opacity animation using jQuery, you can utilize the animate function. By adjusting the opacity value based on the scroll position of the window, you can achieve a fading effect. Here's an example code snippet:

$(window).scroll(function() {
  var scrollTop = $(window).scrollTop();
  var windowHeight = $(window).height();

    $('.logo_container, .slogan').animate({
      'opacity': ((windowHeight - scrollTop) / windowHeight)
    }, function() {
       if (this.style.opacity <= 0)
           $(this).hide();
    });
});
