Q: Uncaught Type Error - fadeToggle/Display, Jquery (It works but still throws the error) So I've got this function; 
function hoverTiles() {
  $('.content-block').hover(function () {
      var $content = $('.content', this);
       $content.fadeToggle(1000, 'linear').display(1000, 'linear');
  });
}

But chrome is telling me I have an Uncaught Type Error even though the function itself is working? If I remove the fadeToggle I get the same error but with display instead.
Any insight much appreciated. Even though it's working I was told never to ignore errors...
console log:

custom.js:82 Uncaught TypeError: $content.fadeToggle(...).display is not a function
