HTML5+jQuery打造漂亮的爱心表白动画

HTML5+jQuery打造漂亮的爱心表白动画，页面左侧会有打字机效果，表白的话语会像打自己一样一个字母一个字母显示，又像代码一样带有注释和着色效果。稍等片刻，右边会用彩色画出一个星形。非常的绚丽。360、FireFox、Chrome、Safari、Opera、傲游、搜狗、世界之窗. 不支持IE8及以下浏览器。
1、在head区域引入css样式：

<style type="text/css">
@font-face {
    font-family: digit;
    src: url('digital-7_mono.ttf') format("truetype");
}
</style>
<link href="css/default.css" type="text/css" rel="stylesheet">
<script type="text/javascript" src="https://5.jimth.com/download/jquery/jquery-1.8.3.min.js"></script>
<script type="text/javascript" src="js/garden.js"></script>
<script type="text/javascript" src="js/functions.js"></script>

2、在body引入下面的代码：
        1)html代码：

<div id="mainDiv">
    <div id="content">
        <div id="code">
            <span class="comments">/**</span><br />
            <span class="space"/><span class="comments">*2013—02-14,</span><br />
            <span class="space"/><span class="comments">*2013-02-28.</span><br />
            <span class="space"/><span class="comments">*/</span><br />
            Boy name = <span class="keyword">Mr</span> LI<br />

            <span class="comments">// The boy wants the girl could well have been happy.</span><br />
            <br>
            <br>

            Baby, I love you forever;<br />
        </div>
        <div id="loveHeart">
            <canvas id="garden"></canvas>
            <div id="words">
                <div id="messages">

                    <div id="elapseClock"></div>
                </div>
                <div id="loveu">

                </div>
            </div>
        </div>
    </div>
</div>

       2)JS代码：

<script type="text/javascript">
var offsetX = $("#loveHeart").width() / 2;
var offsetY = $("#loveHeart").height() / 2 - 55;
var together = new Date();
together.setFullYear(2013, 2, 28);
together.setHours(20);
together.setMinutes(0);
together.setSeconds(0);
together.setMilliseconds(0);

if (!document.createElement('canvas').getContext) {
    var msg = document.createElement("div");
    msg.id = "errorMsg";
    msg.innerHTML = "Your browser doesn't support HTML5!<br/>Recommend use Chrome 14+/IE 9+/Firefox 7+/Safari 4+";
    document.body.appendChild(msg);
    $("#code").css("display", "none")
    $("#copyright").css("position", "absolute");
    $("#copyright").css("bottom", "10px");
    document.execCommand("stop");
} else {
    setTimeout(function () {
        startHeartAnimation();
    }, 5000);

    timeElapse(together);
    setInterval(function () {
        timeElapse(together);
    }, 500);

    adjustCodePosition();
    $("#code").typewriter();
}
</script>
