- Go to Solution Explorer
- Right-click on the Application name
- Select Add-->add new item
- Now in the window that opens, select an HTML page or new Web form
- Rename it to CanvaSshapeTangoAnimation.aspx

Step 2 : In this section we will create the style for the media and create the .css on the media screen. Put the given script in the Head section of the HTML or between the <head>--</head> tags. Here the CSS is used for design purposes.
CSS Script
<style>
body
{
background-color: #66CCFF;
margin: 0px;
padding: 0px;
}
canvas
{
border: 1px solid #9C9898;
left: 30px;
}
#tango
{
position: absolute;
top: 10px;
left: 10px;
padding: 10px;
}
#container
{
background-image: url('blue-background.jpg');
display: inline-block;
overflow: hidden;
height: 365px;
width: 580px;
}
</style>
Step 3 : In this part we need to work on some JavaScript. To fully understand how JavaScript works, download the attached .rar file and run the CanvasShapeTango application.
The whole JavaScript looks as in the following:
<script>
function tango(layer)
{
for (var n = 0; n < layer.getChildren().length; n++)
{
var shape = layer.getChildren()[n];
var stage = shape.getStage();
shape.transitionTo({
rotation: Math.random() * Math.PI * 2,
radius: Math.random() * 100 + 20,
x: Math.random() * stage.width,
y: Math.random() * stage.height,
alpha: Math.random(),
duration: 1,
easing: 'ease-in-out'
});
}
}
window.onload = function ()
{
var stage = new Kinetic.Stage({
container: 'container',
width: 578,
height: 363
});
var layer = new Kinetic.Layer();
var colors = ['red', 'orange', 'yellow', 'green', 'blue', 'purple'];
for (var n = 0; n < 10; n++) {
var mine = new Kinetic.RegularPolygon({
x: Math.random() * stage.width,
y: Math.random() * stage.height,
sides: Math.ceil(Math.random() * 5 + 3),
radius: Math.random() * 100 + 20,
fill: colors[Math.round(Math.random() * 5)],
stroke: 'black',
alpha: Math.random(),
strokeWidth: 4,
draggable: true
});
layer.add(mine);
}
stage.add(layer);
document.getElementById('tango').addEventListener('click', function () {
tango(layer);
}, false);
};
</script>
Step 4 : In this section we are going to become familiar with the body part of HTML scripting. Replace this script from the body section of the CanvaSshapeTangoAnimation.aspx page. Here we pass a Canvas in the canvas tag.
<body style="background-color: #00CCCC">
<center>
<h1>
Canvas Shape Tango Animation
</h1>
</center>
<hr />
<div id="container">
</div>
<input type="button" id="tango" value="Flip Press!">
</body>
Step 5 : The complete code for the CanvasRotatingAnimation application:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="CanvaSshapeTangoAnimation.aspx.cs" Inherits="CanvasShapeTango._Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<style>
</style>
<script src="jscript.js"></script>
<script>
</script>
</head>
<body style="background-color: #00CCCC">
<center>
<h1>
Canvas Shape Tango Animation
</h1>
</center>
<hr />
<div id="container">
</div>
<input type="button" id="tango" value="Flip Press!">
</body>
</html>
Step 6 : Output Press F5
Note : For the accurate output of HTML5 applications, you must have the Google Chrome browser in your PC. Drag and drop the shapes and press the "Flip press!" button to make the shapes move and refresh the page to generate new random shapes, while running the application in the browser.
