How to add easing effect to your animation with jQuery?

jQueryJavascriptWeb Development

To add easing effect to your animation, use the animation speed properly to form it a perfect animation for the web page. Do not speed up animation and you should know where to stop it while using animate().

Here for our example, we have a button that takes you to a textarea to add an answer:

<button class="btn" id="answer">
   Add answer

Now set the fade out property properly to set easing effect.

<!DOCTYPE html>
   <script src=""></script>
         $('body').on('click', '#answer', function() {
            var container = $('.new-answer');

            container.css('opacity', '0');

            $(this).fadeOut('fast', function() {
               container.animate({ height: "200px",
               opacity: 1}).animate({
               height: "170px" });
