解釋：

1、點擊按鈕

點擊按鈕的id是activator：

<div class="content">
    <!-- The activator -->
    <a class="activator" id="activator"></a>
</div>

jquery對應的點擊事件寫法：

$('#activator').click(function(){

    $('#overlay').fadeIn('fast',function(){

        $('#box').animate({'top':'160px'},500);

    });

});

2、關閉按鈕

關閉按鈕的id是boxclose：

<a class="boxclose" id="boxclose"></a>

jquery對應的點擊事件寫法：

$('#boxclose').click(function(){
    $('#box').animate({'top':'-200px'},500,function(){
        $('#overlay').fadeOut('fast');
    });
});

3、消息盒子

消息盒子的html：

<div class="box" id="box">
            <a class="boxclose" id="boxclose"></a>
            <h1>重要信息</h1>
            <p>
                這是一個覆蓋層。<br><br>單擊交叉圖標關閉此窗口。
            </p>
</div>
