使用方法
HTML结构
该幻灯片的HTML结构可以使用一个简单的HTML5结构：
<!DOCTYPE html>
<html>
<head>
<title>iPresenter</title>
<!-- Google Webfonts and our stylesheet -->
<link rel="stylesheet" />
<link rel="stylesheet" href="css/styles.css" />
<link rel="stylesheet" href="css/demo1.css" />
<!-- JavaScript includes -->
<script src="js/jquery-1.7.1.min.js"></script>
<script src="js/ipresenter.encoded.js"></script>
<!-- iPresenter script starter Section -->
<script>
$(document).ready(function(){
$('#ipresenter').iPresenter();
});
</script>
</head>
<body>
<!-- BEGIN CONTAINER -->
<div class="container">
<!-- BEGIN #ipresenter element container -->
<div id="ipresenter">
<!-- The Slides Will Go Here -->
</div>
<!-- END #ipresenter element container -->
</div>
<!-- END CONTAINER -->
</body>
</html>
div#ipresenter用于包裹整个幻灯片。
<div id="ipresenter">
<!-- The Slides Will Go Here -->
</div>
通过这个幻灯片插件，我们可以创建各种幻灯片切换时的平滑过渡效果。插件通过为每一个div设置不同的data属性，这些data属性会转换为真正的CSS3动画效果。下面是所有可用的data属性：
data-easing：easing timing函数(也可接收cubic-bezier函数)。
linear
ease
ease-in
ease-out
ease-in-out
ease-out-in
easeInQuad
easeOutQuad
easeInOutQuad
easeInCubic
easeOutCubic
easeInOutCubic
easeInQuart
easeOutQuart
easeInOutQuart
easeInQuint
easeOutQuint
easeInOutQuint
easeInSine
easeOutSine
easeInOutSine
easeInExpo
easeOutExpo
easeInOutExpo
easeInCirc
easeOutCirc
easeInOutCirc
easeInBack
easeOutBack
easeInOutBack
data-pausetime：slide多久才会显示。
data-x, data-y, data-z：将幻灯片在屏幕3D空间中移动。
data-rotate, data-rotate-x, data-rotate-y, data-rotate-z：沿指定的轴旋转元素，单位degrees。
data-scale：放大或缩小幻灯片。
data-thumbnail：缩略图的url。
示例代码如下：
<!-- The first slide retains its default position. We could omit the data attributes -->
<div id="intro" class="step" data-x="0" data-y="0">
<img src="img/details.png" />
<h2>A phone that sees the world like you do, in 3D</h2>

</div>
<!-- We are offsetting the second slide, rotating it and making it 1.8 times larger -->
<div id="capture" class="step" data-x="1100" data-y="1200" data-scale="1.8" data-rotate="180" data-easing="easeInOutQuint">
<img src="img/ksp1.png" />

</div>
CSS样式
该幻灯片插件中有两个主要的CSS样式文件，一个是styles.css，这个样式表用于生成页面的通用样式，如字体、链接等样式。第二个对应每个demo的样式表，分为demo1.css和demo2.css，分别用于为两个demo指定样式：
/* === Preloader Section === */
div#ipresenter div#preloader {
some styles
}
div#ipresenter div#preloader div {
some styles
}
/* === Steps Section === */
div#ipresenter div.step {
some styles
}
/* === Control Navigation Section === */
/* = General = */
a.ipresenter_stepsNav {
some styles
}
/* = Next Button = */
a#ipresenter_nextStep {
some styles
}
/* = Previous Button = */
a#ipresenter_prevStep {
some styles
}
/* = Pagination Buttons Container = */
div.ipresenter-controlNav {
some styles
}
/* = Pagination Previous Buttons = */
div.ipresenter-controlNav a.ipresenter-controlPrevNav {
some styles
}
/* = Pagination Next Button = */
div.ipresenter-controlNav a.ipresenter-controlNextNav {
some styles
}
/* = Pagination Number Button = */
div.ipresenter-controlNav a.ipresenter-control {
some styles
}
/* = Pagination Tooltip = */
div.ipresenter-controlNav div.ipresenter-tooltip {
some styles
}
div.ipresenter-controlNav div.ipresenter-tooltip div {
some styles
}
div.ipresenter-controlNav div.ipresenter-tooltip img {
some styles
}
/* === Playback === */
/* = General = */
#ipresenter-timer {
some styles
}
/* = When its playing = */
#ipresenter-timer.play {
some styles
}
/* = When its paused = */
#ipresenter-timer.pause {
some styles
}
所有的图片样式都放置在div.step中，你可以自定义它们。如果你要修改它们，只需要找到下面的代码：
div#ipresenter div.step img {
change styles here
}
