Publishing editor Triobo can handle embedded code in HTML5, see HTML object. If you know how to create such simple HTML5 animations, forms, or even games, nothing prevents you from using them on the page of magazine for tablet edition. Remember that the Apple iPad is using the WebKit rendering engine (like Safari or Chrome on your computer), thus observe the required syntax. Any sources that you refer to HTML code will be available in the same imaginary tablet folder, therefore do not enter any pathways there!
Simple example of a rotating logo.
Suppose you have an image named logo.png with dimensions of 180 x 80 px. Create the following HTML code in the folder with the article source on your computer:
<html>
<head>
<title>iframe</title>
<style>
body {margin:0;padding:0;}
#plocha{
display:block;
width:200px;
height:120px;
overflow:hidden;
-webkit-perspective: 300;
-webkit-perspective-origin: 100px 75px;
}
#logo{
position: relative;
top: 20px;
margin: 0 auto;
height: 80px;
width: 180px;
background: #ddd url(logo.png) no-repeat; /* do not enter any pathways nor slashes! */
-webkit-transform-style: preserve-3d;
-webkit-animation: spin 8s infinite linear;
}
@-webkit-keyframes spin {
from { -webkit-transform: rotateY(0); }
to { -webkit-transform: rotateY(-360deg); }
}
</style>
</head>
<body>
<div id="plocha"><div id="logo"></div></div>
</body>
</html>
