网站横幅代码

centerMARQUEE scrollAmount=1 scrollDelay=1 direction=up width=600 height=350

DIV align=centerIMG src="图片网址" width=300 border=0/DIV

DIV align=centerIMG src="图片网址" width=300 border=0/DIV

DIV align=centerIMG src="图片网址" width=300 border=0/DIV

DIV align=centerIMG src="图片网址" width=300 border=0/DIV

DIV align=centerIMG src="图片网址" width=300 border=0/DIV

DIV align=centerIMG src="图片网址" width=300 border=0/DIV/MARQUEE/center

说明：

1，center/center前后代码代表居中的意思，可以居中滚动

2，scrollAmount=1 scrollDelay=1可以设置数值，也就是滚动速度，数值越大滚动越快。

3，direction是方向，up=上，down=下，left=左，right=右，都可以自定义，愿意怎么滚动就怎么滚动。

4，width 宽度，height 高度 也是自定义更改。

你想做什么样的我可以给你做 给我留言就行

网页悬浮图片怎么写代码？

左侧悬浮代码如下：

div style="position:absolute;width:110px;height:455px;top:150px;left:0px;" id="lefimg"img border="0" src="../图片名" width="图片宽度" height="图片高度" //div

script language="JavaScript"

!--

lastScrollY=0;

function heartBeat(){

var diffY;

if (document.documentElement document.documentElement.scrollTop)

diffY = document.documentElement.scrollTop;

else if (document.body)

diffY = document.body.scrollTop

else

{/*Netscape stuff*/}

//alert(diffY);

percent=.1*(diffY-lastScrollY);

if(percent0)percent=Math.ceil(percent);

else percent=Math.floor(percent);

document.getElementById("lefimg").style.top=parseInt(document.getElementById("lefimg").style.top)+percent+"px";

lastScrollY=lastScrollY+percent;

//alert(lastScrollY);

}

window.setInterval("heartBeat()",1);

// --

/script

图片高度和宽度用数字代替即可，层的宽度和高度可自定义

将如上代码加入到网页的/body前即可
