Create a bounce effect on hover

Question

I have to develop a similar website like http://www.unlocknrepair.com/ In this website when you hover your mouse over the Unlocking or Phone repair button a dropdown menu appears. Is there a way to make this dropdown appear in bouncy way.. like I want it to bounce a bit before it stabilizes. It is possible in jQuery, but can it be done using only css and javascript?

Answer 1

Yes, it is possible using native javascript. Take a look at this document
Note, I'm linking to the "easeOut" section, since I think that represents a ball's bouncing a little better than their "bounce".
Here's a good example, further down the same page.

If experimental css3 is an option, you can do it even without javascript using css animations with the @keyframes rule.

 #parent { position:relative; height: 40px; } #onhover { display: none; position: absolute; top: 0; } #parent:hover #onhover { display: block; top: 30px; animation:mymove 0.8s linear; -moz-animation:mymove 0.8s linear; /* Firefox */ -webkit-animation:mymove 0.8s linear; /* Safari and Chrome */ -o-animation:mymove 0.8s linear; /* Opera */ -ms-animation:mymove 0.8s linear; /* IE */ } @keyframes mymove { 0% {top:0px;} 10% {top:3px;} 40% {top:40px;} 60% {top:25px;} 80% {top:35px;} 100% {top:30px;} } @-moz-keyframes mymove /* Firefox */ { 0% {top:0px;} 10% {top:3px;} 40% {top:40px;} 60% {top:25px;} 80% {top:35px;} 100% {top:30px;} } @-webkit-keyframes mymove /* Safari and Chrome */ { 0% {top:0px;} 10% {top:3px;} 40% {top:40px;} 60% {top:25px;} 80% {top:35px;} 100% {top:30px;} } @-o-keyframes mymove /* Opera */ { 0% {top:0px;} 10% {top:3px;} 40% {top:40px;} 60% {top:25px;} 80% {top:35px;} 100% {top:30px;} } @-ms-keyframes mymove /* IE */ { 0% {top:0px;} 10% {top:3px;} 40% {top:40px;} 60% {top:25px;} 80% {top:35px;} 100% {top:30px;} } 

 <div id="parent">hover me<div id="onhover">hovering</div></div> 

Another "bounce" animation:

 $(function() { $(document.body).delegate( "img", "mouseenter", function() { var $this = $(this).addClass("right"); setTimeout(function() { $this.removeClass("right"); }, 2000); }); }); 

 body { font-size: .7em; font-family: Arial, Helvetica, "Liberation Sans", sans-serif; padding: 0 !important; } img { -moz-transition: -moz-transform 1s ease-in; -webkit-transition: -webkit-transform 1s ease-in; -o-transition: -o-transform 1s ease-in; -ms-transition: -ms-transform 1s ease-in; } #anim.right { -moz-animation-name: bounce; -moz-animation-duration: 1s; -moz-animation-iteration-count: 1; -moz-transform: translate(400px); -moz-transition: none; -webkit-animation-name: bounce; -webkit-animation-duration: 1s; -webkit-animation-iteration-count: 1; -webkit-transform: translate(400px); -webkit-transition: none; } @-moz-keyframes bounce { from { -moz-transform: translate(0px); -moz-animation-timing-function: ease-in; } 60% { -moz-transform: translate(400px); -moz-animation-timing-function: ease-out; } 73% { -moz-transform: translate(360px); -moz-animation-timing-function: ease-in; } 86% { -moz-transform: translate(400px); -moz-animation-timing-function: ease-out; } 93% { -moz-transform: translate(380px); -moz-animation-timing-function: ease-in; } to { -moz-transform: translate(400px); -moz-animation-timing-function: ease-out; } } @-webkit-keyframes bounce { from { -webkit-transform: translate(0px); -webkit-animation-timing-function: ease-in; } 60% { -webkit-transform: translate(400px); -webkit-animation-timing-function: ease-out; } 73% { -webkit-transform: translate(360px); -webkit-animation-timing-function: ease-in; } 86% { -webkit-transform: translate(400px); -webkit-animation-timing-function: ease-out; } 93% { -webkit-transform: translate(380px); -webkit-animation-timing-function: ease-in; } to { -webkit-transform: translate(400px); -webkit-animation-timing-function: ease-out; } }
