使用javascript实现的无缝滚动（跑马灯），小编在这里简单描述一下：内容一直滚动，鼠标经过的时候滚动就会暂停。
效果示例图：
实现代码如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>无缝滚动</title>
<style>
img{
width: 100px;
height: 50px;
}
#demo{
overflow: hidden;
width: 735px;
height: 165px
}
table{
}
</style>
</head>
<body>
<div id="demo" class="hdo gd_img">
<table cellpadding="0" align="left" border="0" cellspace="0">
<tbody>
<tr>
<td id="demo1" valign="top">
<table cellspacing="0" cellpadding="4" width="2150" border="0" id="tupian">
<tbody>
<tr>
