今天，我和大家分享一个特效，让大家感到你的“叶子”更加与众不同！
窗口从天而降的效果：给人以为之一振的感觉。实现方法是，先在内空一格后加上“drop(300)"…>”；再在< head>和< /head>之间加入如下代码(这段代码较简单，我就不再多嘴解释啦)：
function drop(n) { if(self.moveBy){ self.moveBy (0,-900); for(i = n; i > 0; i--){ self.moveBy(0,3); } for(j = 8; j > 0; j--){ self.moveBy(0,j); self.moveBy(j,0); self.moveBy(0,-j); self.moveBy(-j,0); } } }

</SCRIPT>
第二步:把如下代码加入<body>区域中(也就是在页面中调用脚本)
<p dynamicanimation8="dropWord"
style="position: relative !important; left: 10000 !important" align="center"><font size="3" color="#ee00FF">很 好 玩 吧 ! 有 没 有 吓 一 跳 ?<font size="7"><b><font face="Arial, Helvetica, sans-serif" color="#FF0000">YES!
</font></b></font></font>
第三步:把<body>改为
<body bgcolor="#fef4d9">
做字幕并非专业人士才能做到的，要想做活动字幕其实也是网页必备技能之一，大家可以做做看。活动字幕是网页中经常使用的组件之一，它能使整个网页更有动感，显得很有生气。现在的网站中也越来越多地使用活动字幕来加强网页的互动性。用JavaScript编程可以实现各种活动字幕效果，所需的代码很少，确实能够以较少的下载时间换来较好的效果。该标记语法格式如下：
JavaScript教程 《marquee
aligh=left/center/right/top/bottom
bgcolor=#n
font=n
direction=left/right/up/down
behavior=type
height=n
hspace=n
scrollamount=n
Scrolldelay=n
width=n
VSpace=n
loop=n》
可以看出由于活动字幕的显示方式多种多样，可选的参数也很多。
Bgcolor：用于设定活动字幕的背景颜色，一般是十六进制数。
Behavior：用于设定滚动的方式，主要由三种方式：behavior=“scroll”表示从一端滚动到另一端；behavior=“slide”表示从一端快速滑动到另一端，且不重复；behavior=“alternate”表示在两端之间来回滚动。
Hspace和vspace：分别用于设定滚动字幕的左右边框和上下边框的宽度。
Scrollamount：用于设定活动字幕一次滚动的距离。
scrolldelay：用于设定滚动两次之间的延迟时间。
Loop：用于设定滚动的次数，当loop=-1表示一直滚动下去，直到页面更新。
《marquee》标记的默认情况是向左滚动无限次，字幕高度是文本高度，滚动范围：水平滚动的宽度是当前位置的宽度；垂直滚动的高度是当前位置的高度。下面是两个通过JavaScript编程实现特殊效果活动字幕的脚本代码：
★带链接的水平滚动字幕★
带链接的水平滚动字幕一般用于广告宣传，非常醒目：
《script language=“JavaScript”》
var marqueewidth=400
var marqueeheight=20
var speed=4
var marqueecontents=‘《strong》《big》欢迎访问《a href=“www.cce.com.cn”》中国电脑教育报网站《/a》欢迎您光临《a href=“mailto:net@cce.com.cn”》给我来封信！《/a》《/big》《/strong》《/font》’ document.write（‘《marquee scrollAmount=’+speed+‘ style=“width：’+marqueewidth+‘”
》’+marqueecontents+‘《/marquee》’）
《/script》
★带链接的垂直滚动字幕★
垂直滚动的活动字幕常用于以滚动方式发布新闻。脚本代码中参数“behavior、derection、width、height、scrollamount、scrolldelay”分别确定了活动字幕的滚动方式、滚动方向、宽度、高度、一次滚动距离、延迟时间等，另外参数“onmouseover=‘this.stop（）’”所实现的效果是当鼠标指针移动到活动字幕上时，字幕停止滚动，参数“onmouseout=‘this.start（）’”恰好与之相反。
