Building an animated 3D poll

Posted on June 10, 2010

Regular readers of Papermashup will have seen the post that I wrote last week on Easy Poll, the personal project that I launched a few weeks back that allows you to create a simple 2 answer poll that you can share and gather feedback on. You can read the post about it and check out easypoll.papermashup here I’d love to hear your feedback.

I thought i’d cover how to create a 3d animated poll using jQuery and CSS similar to the polls page on Easy Poll.

The Code

I don’t usually do this but here’s the complete code snippet so you can see the JavaScript CSS and HTML all in one space. most of the configuration is achieved thought the CSS but you’ll notice that on page load the bars animate to the correct height using the jQuery animate function which we’re passing a percentage height into.


<head>
<style>
.rating {
float:left;
width:180px;
background-image:url(images/poll-bottom.png);
background-position:bottom left;
background-repeat:no-repeat;
padding-bottom:40px;
}

.graph {
float:left;
margin-top:10px;
position:relative;
height:380px;
padding:0;
}

.graph .bar1, .graph .bar2, .graph .bar3{
display:block;
position:absolute;
background-image:url(images/poll-body.png);
background-position:top left;
color:#fff;
width:159px;
min-height:70px;
font-family:Arial, Helvetica, sans-serif;
font-size:12px;
line-height:1.9em;
bottom:0;
}

.graph .bar1 span, .graph .bar2 span,  .graph .bar3 span  {
position:absolute;
left:50px;
top:20px;
font-size:33px;
color:#333;
text-shadow:0 1px #fff;
}

</style>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.js"></script>
<script type="text/javascript">

  $(document).ready(function(){

  $('.bar1').animate({'height':'22%'},500);
  $('.bar2').animate({'height':'58%'},1000);
  $('.bar3').animate({'height':'88%'},1500);

  });

</script>

</head>

<body>
